Hi all,
I noticed something odd that might be worth sharing. I never had issues with the new sonos app. My app loads in about a second (at least with recent updates).
That said yesterday I started having issues when trying yo stream from tidal. And I also noticed that opening the sonos app took now 10 seconds or more. The problem continued this morning.
At that point I realised that the sonos app had a “playlist” in my history, probably because I started a song from there few days ago. So I tried to delete the playlist, so that now my history says “Your recent history will show here once you've played some content”. And bam, now the app is back to start in s second or so, and the problems streaming from tidal are gone.
Is it possible that the people running into issues with the sonos app are using it more for streaming music, as opposed to stream from external apps? If you have issues, I wonder if clearing history is something worth trying: it made a massive difference in my case (even though it doesn't make much sense).
