Cannot get into app, says "Under Maintenance"


Please can someone let me know what is going on.
I cannot get into my app.

We are way past the scheduled maintenance window, yet my app keeps saying “Under Maintenance, olease try again in a few minutes”.

I cannot perform any of my day to day business.

Please help


Removed the app, and re-installed it.
It seems to be working now.
