ColorNote trouble?

I use ColorNote on my Samsung phone.

Yesterday, I was in the middle of editing a note and the app refreshed and all of my notes were gone.

I went to backup and it said I had a backup on device with 1021 notes (which is accurate, because I've been using the app for 5 yrs).

When I click "view" or "restore" it prompts me to sign into a Google account. It shows a Yahoo email on file, though.

If I sign in with a Google account, it does not let me restore the old backup to the new account, or sign into a different email.

I'm stuck in this loop of being prompted to sign in. My notes still exist in this back up file, but I can't seem to restore them or import them at all.

Does anyone know anything about this or is there any solutions you've come across? Thank you.
