For anyone that has verification issues I solved with this steps
Sign into Coinbase at https://www.coinbase.com/signin. If you're already signed in, please log out and start fresh. If you run into a Verifying Your Documents error page, please click the "X" in the top right corner, and that should allow you to proceed to your Coinbase home screen.
Once you've signed into Coinbase and are at your home screen, then in your URL bar in your browser replace https://www.coinbase.com/dashboard with https://www.coinbase.com/verify-identity and navigate to this page. At this point you should be able to enter in your current legal information as it appears on your government issued ID documents. This information should match your legal name, address, and date of birth. If you run into the same error as before, please click the "X" in the top right corner and attempt to load the https://www.coinbase.com/verify-identity page again.
Go to https://www.coinbase.com/verify-documentand complete verification again.
Für alle! Bei mir funktioniert es jetzt wieder reibungslos und ich bin erfolgreich verifiziert👍
