I am seeing this issue but slightly differently. I am getting Safari (Purple Safari Tech Preview on Mac OS 12.1) suggesting passwords overtop of 1Passwords extension rendering the extension unusable. How do I fix this? I have all the password stuff in Safari and iCloud turned off and this did previously work.
Thanks for letting us know about this. We're investigating and figuring out exactly what could be causing this when using Safari Technology Preview.
Additionally I've split off your post into a separate thread as this appears to only be happening when using Safari Technology Preview, not the regularly available Safari. :smile:
