1Password is Broken with Duo Mobile

I had done a Full Reset of Settings on my iPhone. After that, 1Password 8 and 7 didn't work anymore. 

I Deleted and reinstalled both Apps and it still doesn't work. Every time I tried, 1Password would go into a loop of wanting to use Duo to Authorise 1Password.

I cannot get past the Authorisation loop. Currently I have only 1Password 8 for iOS installed.

Nothing is working. Setting up a New Account via QR code is broken too.

Before I deleted the Apps I could use 1Password Offline but it's it's unusable now.
