I'm an admin for my organization, and over the past few days I've been getting a lot of support complaints about Teams chat not working on Android phones. As of last week, it was working for me, so I suspected it was a phone specific problem. However, when I first opened the app today I noticed that all my chats and functionality suddenly disappeared. The only option available in the teams app seems to be calling.
I checked the org policies, and everything is correct. This looks to be a bug on the latest version of the app.

I managed to get to "activities" by trying to save a photo to the teams app, and when I bring this up it says "Administrator has disabled chat for this user." I'm the admin, and I certainly didn't do this. All policies under messaging allow for chat. 
Please help!
