The thing with this is that after shutting down Mixer, Microsoft started suggesting people to stream on Facebook Live instead. I’m still not sure how that partnership lead to the trademark of Mixer being given to Facebook Inc. at the time (I assume, before they became Meta).
Gestures aren’t very convenient if I’m watching videos in full screen mode or when typing on the keyboard. There are many problems with gesture nav in Android, let alone MIUI. It’s not worth keeping the default launcher for this.
