Yhea that's the problem I don't want my phone to be unlocked. But ok thanks anyway I think I'll just give up hahaCould add a Wait Until Trigger action with a trigger of Screen Unlocked, before doing the UI Interaction action, but ... if the goal is to have this happen on your phone even if you're not near it, or don't want to unlock it, I'm fresh out of ideas.
One can send an intent to Spotify to display a playlist, but I've never seen an intent to start playing one.
Hopefully someone else knows that part.
