Accessing and using Microsoft Teams on smartphones and tablets across platforms
I am having the same problem with Teams and Wifi.
So I did some more testing.
I signed-out from my account in Teams while on LTE. Closed the app. Turned On Wifi.
When trying to reconnect, I get: "There was a problem with the network. Try signing in again."
Wifi Off=> Sign in no problem.
Connecting to Teams on Chrome on the same phone (Pixel 4a), while connected to Wifi. I get to login, but then there is a message that the browser version is not supported.
On a Windows PC, Teams App and in-browser https://teams.microsoft.com/ work just fine while connected to the same Wifi.
