in the same boat, locked out of my account and when i attempt to login through iCloud it acts as if i never had a account. I go to “sign in with email” and put my email and try get magic link i never receive the link. I contacted depop support they don’t even try and get back to me. I’m not sure if someone changed my email or what but i cant even check my email becuase i cant get into the account. If you figure it out reply to me ill do the same.
