I've been using it since the Pixel 3 days. Tap to pay doesn't work, and some people have reported banking apps not working, although my banking apps do work. Also, certain pixel-exclusive features like now playing don't work. And you are going to need to install play services or other Google components if you want stuff like notifications in various apps or text-to-speech and speech-to-text in the browser, etc. Aside from that, it's incredible. Works perfectly.
