No reliable Autofill in Safari even when 1PW is unlocked

My 1Password has become unreliable and unpredictable too, since I switched from a standalone license to a membership with 1Password 8. As a standalone it always worked as expected. Now sometimes it works, or it works after I dismiss the popup and click the 1Password icon in then Safari title bar a 2nd time. Sometimes it will only work if i quit and relaunch Safari. And sometimes it just doesn't work no matter what I try - and these are websites that I have been logging into every day successfully for years until now. I am getting frustrated with 1Password customer support - they have nothing constructive to offer except "visit our Community" so here I am visiting the community. Can anybody give me a reason to stick with this product?
