YouTube Music still hasn’t got a “Delete Queue” button. Google Play Music had it, every other streaming service I tried has it, I’ve written them numerous times to request it - nada.
There are a variety of other issues, and they do nothing when you give feedback. Just care about getting your subscription $$$, and even not enough as other services as to try and stop you with some incentive when you unsubscribe. You said it best - Ytm is so ass.
