Ever since its appearance in Android Pie, I always consider 2 button navigation is a bad attempt by Google trying to play catch-up with the fad generated by the iPhone X. However, due to a bug with A13 QPR2 it had to be temporarily removed and many were not happy about this. So, 2 button navigation users, may I ask why do you prefer this method? To me it makes you do more for the same action whilst doesn’t save any screen space.
I’m not using two-button navigation but there was one nice thing it did in Android 9: you could flip the pill to the right and hold it to scroll through open apps until you’ve reached the app you wanted to switch to (or move your finger left/right to scroll in that direction), and only then lift the finger.
Unfortunately that only worked in Android 9. In Android 10 you could only swipe to the very next app. Not sure why they butchered that carousel navigation; probably to bring it in line with full gesture navigation.
