Skype to teams migrations

We are converting our user base from Skype to teams, a few things that are standing out as issues:

1) sync between mobile and desktop, still not working, skype goes away next week, when will this be fixed, HUGE ISSUE for user base

2) Some users are reporting that when they respond in a chat, that their reply is showing up above the next statement from the other participant, its very confusing and fastly becoming an issue.

3)Emoji's, will these be changed to a non-animated emoji? :)

4) issues installing and getting messages about "personal accounts not allowed" not clear how to get around this isxue, generally windows updates/uninstalls multiple times and eventually it works?

Thanks for any ideas on these issues!
