I am using Samsung Galaxy M21. I have been trying to log in for 10 days, but I am facing a credential issue. Although I am using it in logging in a laptop with the same credentials and it is logging successfully. Can anybody help me ?

Thank you for the feedback, would you be able to help reach out to your System Administrator to help with the logging issue?

YMMV but it was unusable for me. Constantly refuses to connect to server. I *might* get logged in but then it's all downhill from there with multiple connection errors. Most of the time can't even get it to log in. Network is fine, no other apps experiencing this. Tried uninstalling and reinstalling multiple times but no good. Tried adjusting settings but no good.
