Where is auto play?

Been subscribed for a while now (year plus) and have used auto play frequently, until today. It seems to have disappeared. I tried an apple.com help thing that said to play a recommended playlist and it reappeared, but as soon as I played some foo fighters (not apple recommended) it disappeared again.

Also have cleared history and turned my phone off and on. Still not there. Posting because google isn’t helping. Have a 12.
