I use Android's navigation gestures, so to go back I have to do a swipe starting from any edge of the screen (left or right), but doing this from the left edge also opens the sidebar which is not the desired behavior.
I suggest implementing the standard behavior that has been adopted by other apps lately, in which you have to do a long press on the edge for 1 second in order to activate the side bar and be able to swipe to reveal it. You can see this in Google apps, Gmail for example.
This is the only video I could find with a demonstration (minute 2:00): https://youtu.be/KUMOPuBUqJ8
Yeah I have that enabled, but I keep swiping from the edge due to the habit of doing that on all other apps.
The other option I have is to disable the sidebar and enable bottom bar navigation, but I don't like that option completely because the bottom bar doesn't auto-hide when scrolling.
