No access to app

My app’s URL:
Unable to login with any email id onto the app. Changed the link to an older version of an app and it crashed suddenly. Not allowing me to login now. Hoping my users won’t face the same issue.

I noticed that I cannot login with another email either. The icon on my mobile is also crashing and it returns a message saying “not found”

I was able to sign in.

I’m able to sign in as well. Are you still seeing this issue?

It started working now. It was down for sometime and I started to panic. Thank you!
