Won’t connect to the sonos after apple update. – Sonos S1 Controller Review

My sonos won’t play any selected music since my iPhone updated a couple days ago. The app sees the speakers and can group them and everything else but play music. I factory reset one speaker and it seemed to work temporarily but now in the same situation again. Is this an issue that anyone else is having on a regular basis?
