A lot of the time when I'm on my mobile data and on Wifi, my messages often aren't sent. They remain in the unsent state and I need to restart Teams, which doesn't always work. There's nothing wrong with the Wifi or my data, and I don't have this issue with other apps.
I've also ask other people on my team, and no one else has experienced this issue.

Repro steps:
1. Open Teams
2. Send a message to someone
