I have a similar issue. I have a Samsung Galaxy S10. The controls on my lock screen work. I can pause and skip tracks. But if I pause on the lock screen, and the screen display turns off after a few seconds, the lock screen controls are no longer there and I cannot resume play. I have been an iPhone user for the past 5.5 years, and only got the Samsung yesterday, so any help would be greatly appreciated!
This is not "solved." Every thread on Spotify Community has it marked as solved...
I confirm I am also having this issue and have had it across two phones, Galaxy S8 and currently S10. Like with other users, a reinstall or re-log in only temporarily fixes the issue. Very frustrating.
I can confirm that I'm having issues with my Galaxy S10 in specifically pausing. It sounds like it pauses and plays it immediately, so my attempts to pause just skips the song for about a second. I'm starting to think that I should move to Google Play Music, since that works perfectly fine.
