Microsoft updates Calendar on Windows Phone 8.1, introduces serious bug

With Windows Phone 8.1, Microsoft reworked its mobile operating system into something more modular, making it far easier to update elements that, previously, were deeply integrated into the OS. Components like the Xbox Music and Games hubs were disentangled from the core OS, and reestablished as apps that could be improved more regularly than the infrequent OS updates.

Calendar is another example of this modular app-based approach to OS features, and the latest update to the Calendar app for Windows Phone 8.1 was pushed to devices in the last few hours. Unfortunately, this update has introduced a serious bug which renders the app unusable for many. 

As noted tech journalist Simon Bisson noted today, the Calendar app now crashes as soon as you try to create a new appointment: 

WindowsObserver.com's Richard Hay also pointed out that the same thing happens when you try to edit an appointment: 

We have tested the Calendar app on a range of devices running Windows Phone 8.1 Preview for Developers, and on the Lumia 630 with Windows Phone 8.1 and Lumia Cyan firmware. On each of these devices, the same thing happened every time we tried to open or edit an appointment - the app simply crashed and threw us back to the Start screen. 

The Windows Phone support team are aware of the problem - in a response to developer and blogger Shawn Wildermuth, @WinPhoneSupport told him that they are working on a resolution, but did not elaborate further: 

Until Microsoft sorts this issue out, though, there is one workaround that you can use in the meantime: Cortana. We've tested creating, editing and deleting appointments in the Calendar using Cortana voice interactions, and all of these functions can be performed without issue. 

While this solution is not exactly ideal for those more accustomed to making quick text edits to their Calendar appointments, it's better than nothing until Microsoft resolves the problem.

For what ever its worth when I looked at about 4PM my wife's had checked for an update 16 hours prior and mine 8 hours prior. So it was sometime in between that they released the screw up.

The really weird thing is that is happening to my Lumina 920 but not to my wife's. Both are set for automatic updates and are running 8.1.

Since I was near my laptop I used Outlook for the changes and then let it sync.

[discussion intercepted in Redmond campus, Building 101, 3rd floor, yesterday afternoon]

- Hey Joe, do you want to run this final testcase for the new build of the calendar app before I press the button to push to those jerks outside the walls of our campus?
- Are you crazy? F*ck the testcase! Its already 5PM, the match is about to begin in 30 mins, and I still have to drive home first. Anyway, the update will only be available for those impatient jerks, who cannot wait 10 months between minor patches and signed up for this developer preview joke! Let them eat what we cooked for them! They deserve it! Ok, I am logging out, see ya tomorrow, we will run the testcase for the next build sometime in August, cannot be anything important missed out anyway..

And this is why I have auto-update turned off and always wait a few days before installing updates.

Indeed, unfortunately after I did a hard reset to fix the battery drainage with WP 8.1, drainage that was fixed BTW, I forgot to turn off the bloody auto-update so for now I brought back my HD2 with WM 6.5 and Pocket Informant Calendar.

Its depressing. Having the same issue on the Lumia 1520 too! Everytime I try to love Windows Phone - I find an issue not to - but I guess thats what developer preview means.

Why are you even surprised? Developer Preview is not a great option for a daily driver phone that is primarily used for call/text/etc. Use it on a backup phone or as a true developer would (to test out their apps). This goes for not just WP8.1, but for Android L, and iOS8.

I still think it's just somekind of beta testing there until the wordwide 8.1 rollout gets started... even if there are phones out there with factory loaded 8.1.

This should not be happening. Hope Nadella actually becomes aware of the issue and takes appropriate action (just as Jobs would have - forget arranging a manager to deal with the problem with his team).

I'd be quite surprised if Nadella turned out to be that much of a micromanager

Jobs would have called the team into the office and said - F* You ...he did that for the initial icloud/@me.com team years ago.

'Discipline' did get Apple ahead during the years Jobs reigned. I'm not afraid to say that Apple's slowed down recently (Jony Ives included). Remember back in the late 90s when they completely revamped their product line over a year or two (and every few years following)? Compare that to now (excluding the new Mac Pro).

I sometimes wonder what the monthly percentage of traffic is to social media sites like Facebook at companies like Apple and Microsoft...

I guess little to no testing of the app. I mean how the hell does an app's basic functionality cause a crash and it not be spotted before pushing the update out.

Maybe the wrong build went out? It's happened for other apps before that I remember, not from MS but other 3rd party developers.

I do have the calendar bug, but Bing Weather is funky too when you swipe the main pivot control. It flickers and jumps back to the first pivot every time.

If you are syncing to Outlook then you can create appts on your PC (if you are near it!) and they show up on the phone within a few seconds.

you can also use your Windows Phone 8.1 IE, going to outlook.com and change the calendar there if you are not near your PC.

The Skype and Xbox teams combined must developed the update.

You don't give them enough credits. Indiividually they are perfectly capable of screwing up any update no matter how small.

Well Microsoft never were good in calendar. One would think contacts birthdays would all end up perfectly in a calendar.. never worked 100% not even on Windows Mobile. The Cortana workaround obviously just works with region set to US
