Tapping the "Passwords" prompt above the keyboard does nothing

I’m now having intermittent issues with the 1Password Safari extension “unable to communicate with the app” and Autofill not functioning at all.

Edit: I read in another thread answered by Dave that clearing the Safari cache / history can help. It sure did. For anyone else: turn off autofill, turn off extension, wipe all history / cache data, force quit Safari, turn on autofill and extension.

Thanks 1P_Dave
