Hi dadbody00,
Did you finally get access back to your Coinbase Wallet?
I got the same problem.
Somebody told me there is perhaps a solution. Somebody qualified might access to the motherboard of the iPhone and get the recovery data files in order to restore access to the app with former credentials.
Like setup a former version of the Coinbase Wallet before the incident.
Some of you guys have heard of something like this?
Cheers
