When I open 1Password on iPhone it prompts for two-factor code. I go to Authy and copy the 1Password Code (yes, I confirm it's the right applications) and past it into the box. 1Password briefly flashes my library, then returns to the Two-Factor page and asks for the code. Sometimes it requires my master password to continue.
I just used Authy code to log into my Web account on the mac, and my Mac 1Password installation is working fine.
I restarted the iPhone and now my Master Password is not working on iPhone.
1Password Version: lastest
Extension Version: Not Provided
OS Version: IOS 13.3.1
Sync Type: iCloud
Referrer: forum-search:2 factor does not work in IOS, but does on Mac. Using Authy. It worked prior to today.
