This sort of happened to me. At some point waaaay back I was clicking around gmail and figured out how to create a custom domain. But for some reason I didn't do it for myself, I did it for my mom. So for over a decade my mom had her own custom domain on gmail. And by this point I don't even remember how I did that. But now Google emails me saying I can't do that unless I pay them, I need to have some sort of payment info or they'll close the account. Fine, I migrated her over to proton quickly, helped her set it up and done. They just did the final close of the old account recently. They gave me plenty of time and warnings to solve this. Unfortunately whenever I tried to login with what I thought was the admin account, gmail just said it wasn't the admin account. So I really had no chance to investigate further.
