Advocate IIISame happening here in NJ!!!! Very frustrating! We have been experiencing this for a few weeks and thought it would correct itself but it hasn't. We just logged a ticket with Microsoft.
A quicker way to get it to work is click on Ctrl F5 (together). Then click on app and is should launch.
