"fuelly user credentials changed" - All 3 vehicle data is gone

[Eno45]

PROBLEM SOLVED. Read below on the 2nd post. Basically my email somehow was off by a digit but I was able to sign in with user name which allowed me to see this. All updated and working now and data is back. Backup exported.

Returning from our weekend vacation I filled up gas and was happy to see I was getting better MPG than I thought while towing. APP is working fine no issues. 4hrs later I fill up near home and it now states "fuelly user credentials changed" and I need to log in. I use the same common password for this minor stuff and nothing is logging me in. I then try resetting option and my email doesn't show an account or any of my email accounts. I sign up for this forum with the same email address and now the app signs in with this email but my vehicle data is gone. If I can't get this back I can't see myself continuing to pay for this yearly. I had so much vehicle maintenance photos, data logged into this!!

Why would this show no account out of the blue?

This is the exact error I get on the APP.
