Still have the same issue 5 days after getting a new phone. Log in credentials work on my old phone, my laptop, and my PC but get rejected in my new S21 Galaxy.

What do I have to do to get tech support to fix this problem?

I have been trying to log in to rocket chat on seeking alpha for 5 days getting this same

"OOPS" message despite using accurate log in credentials. Why can't this be corrected?

This appears to be a common and ling standing issue. Fix it!
