Spotify stops playing when iPhone screen locks
I have an iPhone 11 and am on iOS 14.5.1.
I have been using Spotify with this phone through wired headphones for the entirety of lockdown and had no issues - suddenly today (10 May 2021) when my screen goes to auto-lock the music pauses and only comes back on if I unlock the phone and go back into the Spotify screen, it won't even play if I use the play button displayed on the screen whilst the phone is still locked.
Please can someone help, this is so frustrating.
Thanks
