This issue persist majority times. I suspected the issue might be with internet speed. But during that issue occurrence - I tried downloading a large file and it downloads pretty fast and all other apps also connects well except Teams.
Note: Also on the same Home internet WIFI - we have 3 devices connected via Teams (diff IDs) same time and Majority of the time issue resolves after disconnecting 2 other devices. But this way our work/calls gets impacted.
Thanks.
