No, it’s working okay here on iPad/iPhone/Android tablet - maybe try resetting, or reinstalling the App. If the issue persists, maybe try a different mobile or tablet, if you have one handy or can borrow one, just to test if that might work.

If still no joy after that then it maybe best to reproduce the issue(s) seen and immediately submit a Sonos system diagnostic report from within the Sonos App (if that’s possible), note it’s reference and contact/chat with Sonos Support Staff via this LINK and see what the Staff can perhaps suggest to help you to resolve the matter.
