Linux Mint 19.2 Tina Spotify 1:126.96.36.1992.gbd112320-37 claims it's behind firewall and stays in offline mode. Computer is most definitely connected to Internet, all other software works and disabling firewall changes nothing. Rolling back to 1:188.8.131.526.ge08ef575-19 immediately solves the issue and Spotify works as expected.
I have the exact same issue although the Spotify application can act as a remove control for the web player if the app is launched after I start playing music in the web player.
How did you install a specific version? I've installed Spotify via Snap and
> snap info spotify
tells me that it's tracking latest/stable and gives me a list of the "latest" channels, where the stable, candidate and edge are the same version as the installed one (184.108.40.2062.gbd112320-37) which doesn't help much.
Same problem here, @Spotify. I'm using the linux version for quite a while, and this update seems to be unable to correctly detect if there is an internet connection available. I'm also connecting and disconnecting from VPN quite often, but this was not an issue with the previous version.
