Hi @Murilo Teixeira - COINOV ,
Does this issue persist all the time?
Does anyone else have the same issue in your organization?
To exclude the client issue, we firstly recommend you try to login in Teams web client to see if the above issues can be reproduced. If there is no issue in Teams web client, it recommends you try to follow these tips to clear your client cache file:
1.Fully close Microsoft Teams
2.While holding the Windows key, press R to open Windows Run, then copy and paste the following into the box and click OK:
%appdata%\Microsoft
3.Find the Teams folder, then right click it and select Delete
4.Relauch Microsoft Teams.
