I feel your pain, it's flipping inconsistent and to be honest, I know we have a pretty sweet mobile skin, but it lacks many, many features that are either subjectively or objectively important.
I think in the smartphone age and some phones even getting as big as past 5" and the most common lower limit being 3.5", we should definitely get more features even at the cost of a tad more scrolling or so.
It's pretty ridiculous especially considering how there is no action taken whatsoever to either support Tapatalk (I know why, no problem), IPB Communities App is a non-working piece of crap and a dedicated Neowin app, now that'd be AWESOME, but likely won't ever happen.
And yeah, the switch to full version button is beyond ridiculous, might as well remove it altogether as it's just not working at all any time on my end with ANY browser or ANY phone I tested it with.
Step it up!
I know the devs are probably not doing nothing on Neowin and they have lives of their own, but if such show stopper problems exist for such a long time, it raises some eyebrows at least.
