Ask questionsLooking up 2FA codes (mobile) restarts Fenix pair workflow
It is difficult to add new devices to an FxA account with 2FA since the process often restarts when switching mobile apps to check 2FA codes.
Either firefox.com/pair should not ask for 2FA before the mobile device confirms, or reloading Fenix from launcher should provide the confirm button again.
Sync process starts all over and a new QR code and 2FA code are needed. Workaround is press confirm on mobile before following the 2FA steps on desktop.

This is still a problem. Adding mobile devices to FxA still has a lot hurdles if 2FA is enabled.
