Since the firmware upgrade to 15.19 (last night), I am unable to listen to music (spotify) on my 255.
Headphones are connected via bluetooth and I don't have to be in an activity or anything. When trying to play music it is very quiet and stutters so badly that you can't make out any words.
I've tried re-syncing the music, reconnecting the headphones and restarting the watch. Nothing seems to fix it.
