I tried and it still doesn't work. It also doesn't work with some other apps like Interactive Brokers and many other apps like the VPN app reported by other user.
The problem with the current approach is that there is no way to force the auto-fill dialog to appear. Previously I was able to tap on a Enpass notification and it opened autofill dialog for me. Now, if the app doesn't detect the autofill capability, I'm stuck. With older version I had an option to force the autofill dialog to appear.
BTW, do you know if APKMirror is a safe place to download older version of the app?
It's stripe.com. When you refund a purchase, the website asks for a password. The autofill popup appears, but if I click on it, it enters my email into the browser's address bar.
