Microsoft Teams Sign in Banner appears intermittently

Hi All,

This is regarding the "Sign in" banner coming in Microsoft teams, which appears intermittently and once I selected the "Sign in" automatically that banner will disappear.

After some time, the same issue repeats. I would like to understand, is this something a known issue which Microsoft is working, or this can be fixed.

We are using GSA for M365 profile, obviously Microsoft team's traffic will not be routed by default through GSA, however I would like to receive all your thoughts on this.  

If you could also point me to any logs which can reveal the cause for this issue, it would be really helpful, I will analyze the logs and try to identify the cause for this issue.
