Usertesting mobile app not working?

Is UserTesting app not working?

I was accepted for a test earlier and it got stuck at "accepting test". Later on, it would say "something went wrong, please try again". I've contacted support so that I can take the test again and this time it re-appeared. However, I'm stuck at the same page now and it's not accepting again.

Did you guys have any success in accepting mobile tests today??

Thank you very much.
