The first one is a known bug, recommended to turn off ok google detection. The second is not a bug. In android 11 media folders are moved to /sdcard/Android/Media wherein every app has its own directory and other apps don't have automatic access to read or write onto these directories, which is why your gallery app can't see them.After installing the rom, after a few days of use, I detected two bugs and I would like to know if it's just me that this happens! The first is that when I leave the google assistant activated, to detect the Ok google, the microphone doesn't work in apps like whatsapp, telegram or messenger, it doesn't even work in the recorder app. The second bug I found is that the photos folder from whatsapp does not appear in the gallery at all! I've already checked if it had a .nomedia file, or some permission not granted, but everything ok.
