I enabled fast charging on m21 2020 edition.. still it's showing cable charging while charging the phone.

when i am trying to access the voice match of my google assistant it says that it looks like you have already set up voice match on google on another device

whenever i connect my phone to a media player through bluetooth every audio is playing except YouTube. even "youtube music" audio is playable...but youtube is playing only on my phone , not in the externally connected media player
