I bought my One SL in august 2020 and have had the same issue since. I have two rather big issues that spoil my experience.
First off is connection to my One SL. When I use airplay(from Iphone or Macbook) to play Spotify and pause the music for more than 1-2 seconds, the connection seem to be lost. Whenever I try to resume the playback, Spotify shows that music is playing but no sound is heard. What I have to do is disconnect from the speaker(I simply change output on my Iphone/Macbook to the built in speaker) and reconnect to it and playback works fine. Is this how the service is intended to be used?
Please not I’ve tried with both wired and wireless connection. I’ve restarted all devices multiple times, reinstalled software and reconfigured the speaker.
I also have troubles playing music through a service with the Iphone app. First time I try to stream something it loads for a few seconds, and then says something like “Can’t play <song>. Lost connection to <service>”. I have some sneaking suspicion that these two issues are related.
A friend of mine has the One SL too and he experiences no issues at all. I’ve used the One at my office and that works perfectly fine too. I feel like I have a defect device or something.
