Google still hasn't fixed delayed notifications on Pixels, but you can try this

You're the second person in this thread to try convincing me to switch.

I use the app switcher constantly. I'm using it now to jump between my Lemmy client and YouTube. It works. It's fast. The back navigation also interferes with productivity apps, many of which still use a drawer. I use those apps constantly as well.

Gesture navigation will never be a proper use case for me.
