I tried the new release now (thanks by the way!) and can unfortunatly confirm this bug report. PIP on Mi9 with Google Maps not working (same bugs as before). No big deal for me, just as info!
Edit: Just saw that clean install fixes it.
Same here // Mi 9 (global 6/128)
EDIT: I got this fixed, simply bei downloading the most recent Netflix APK from APKMirror (official version) and installing it - just works (IDK if it is necessary, but I also have Magisk installed and Netflix is in the MagiskHide list).
