you expect a build that was leaked to sync? when the server isnt expecting 8.1 to be released yet
plus it might be good idea to be using your account with a leaked product.
Personally, if something doesn't work on a leaked release I just say to myself, "what should I have expected?" and I will probably let it go. That said, there's no harm in asking for help, especially if someone has
been able to get the synchronisation working.
Also, I think you meant to write that it would be a good idea to not
be using his account with a leaked product, but if you meant what you said then I would be interested in hearing your reasoning.
So the question is, is it generally known that synchronisation isn't possible yet, or are there some people that have found a way to do it?
