I’m not sure if this is specific to VoiceOver users or not (a quick google suggests perhaps not, but all those results were from months if not years ago) but it does create some issues with VoiceOver anyway.
Whenever my Apple lightning headphones are connected to my iPhone XR running iOS 13.2, the screen will not lock when spotify is playing. It doesn’t matter if I lock it with the lock button or it auto locks itself. It continually re-awakens and displays the lock screen. This doesn’t happen when I’m playing music through the phone’s (amazing) speakers or indeed through my AirPods either (but sometimes it’s more convenient to have wired earphones when out and about).
The only solution I found on Google (switching off Canvas mode in the Spotify settings) hasn’t worked.
Does anyone else have this issue and/or know how to fix it?
