Restore Not working

I backed up my data on my old phone and copied the json file to my new phone. But restoring this file is Not working and I cannot See any error message.

I used another account on my old phone and had to switch to my google account on my new phone in the Moviebase app, as I had issues with my Premium membership.

Can someone help or give me a hint what I can Do?

Thanks in advance.

The data are normally bound to an account. If you send me the json file in a private message, I can have a look.

Thanks, I have sent the file and the names of the Accounts to your Email
