iOS 15 extension incorrect password

Hello. I have just upgraded to iOS 15 and the latest 1Password and I am getting similar behaviour. In the 1Password app I can log in without issue, but in the Safari extension I get "Incorrect Password". I think this is related to my business using Duo for MFA. If I put my Duo account into bypass mode I can log in to the Safari Extension without issue using my Master Password. But if MFA is required I get "Incorrect Password" despite knowing it's correct (I'm cutting and pasting it in as suggested in your help guide, and it works in the 1Password app). I have spoken to our internal 1Password support folk and they asked me to put a post on this thread. Kind regards, Alec
