Ill start I NEED to be able to play audio on a Mobile device when the screen is turned off youtube makes you pay for that 1 line of freaking code! Heckin BS
If you want to play YouTube in the background on iPhone check out vinegar.

You can have it with Firefox on iPhone.
Or the Brave browser will let you! And Picture in Picture!
