Teams mobile app for Android loading just a few messages per conversation on work profile

Hello all, asking help on the following:

User at my company is having issues with Teams on work profile. All conversations are displayed, but only a few messages per conversation are loaded. 

-Issue started about 2 weeks ago. 1 month ago it was working fine.
-Almost all conversations get 'sliced' daily, but not all of them. Some conversations have messages from a month ago. To further explain this.. if the user keeps chatting with X person, the older messages start to disappear, leaving only those from about 12Hs-24hs ago. If the user doesn't chat that often, then messages are retained for longer. Some chats have messages from 1month ago but it seems that only because there are very few messages in said chat. However if user logs in Teams Desktop or Web, all messages for all conversations are loaded without issues. 
-User already tried setting up his account in multiple phones (3, all Android) and the conversations show the same amount of messages.
Interesting to note is that when the account is setup, the conversations show a little bit more messages but after closing Teams app and reopening, it shows less messages and doesn't load anymore.
-Issue seems to be with message loading rather than messages being deleted since both Desktop Teams and Web Teams load all messages properly. The issue is happening only in Teams mobile app.
-Outlook for Android is working properly with the same work account.

-Already tried all the basics (clear cache, reset DB, sign out, sign in, remove Company Portal and Teams and install all again, try in different phones, etc).

Thank you!
