My Question or Issue

I'm able to play Spotify using the Sonos app, but I can no longer connect to Sonos using Spotify Android app. Reinstalling Spotify did not help. Starting song through Sonos app, then opening Spotify app also didn't help.

Not sure whether I solved this myself or in collaboration with Spotify tech support. Support asked me to (1) reset offline devices, (2) do a clean app reinstall, (3) soft reset my device, and (4) log out and back into Spotify. These steps didn't help. But then I unplug my Sonos speakers, rebooted my wi-fi, replugged my speakers, then went through each of supports steps. After doing ALL of that, I was finally able to connect to Sonos from my Spotify Android app.
