this annoys me as well, why would the app decide to log me out, when it cannot connect to the backend? I have playlists downloaded for this exact reason...

This is why you should just say NO to DRM.

Same, it logged me out and can't log back in. I have dozens of hours of music downloaded on my phone for this exact reason... And I bought Spotify premium for this exact reason, to listen to offline music. What a shame.

It logged you out while in "airplane mode"? How did it decide to do that?

Genuinely curious, I don't use it but would have expected offline things to continue as they were while cut off from the rest of the network.

I was not in airplane mode, but we were 20k ft above ground. It logged me out about 40 minutes into the flight which makes 0 sense to me.

To be fair to Spotify it never happened to me before. Maybe it’s their DRM that just locks you out if it can’t reach the server with a timeout of 1 hour or so (1 hour conditional on the last attempt being a failure).

What makes you think they were in Airplane mode?

I feel you. I’m about to board a flight and Spotify logged me out while I was listening to an offline playlist.
