My son recently downloaded the Sonos app to his new Android. Apparently, he was prompted to update the Play 1 speakers I bought last year. That rendered the controller on my iPhone 5 unusable. This happened to me once before, when he did the same thing on what was then his iPhone 5. That fubar’d the contoller on my Blackberry 10. So I bought a used Kindle Fire, on someone else’s advice, which turned out to be incompatible. A few months later, I inherited his old iPhone.
I should have stopped him!
