This usually happens if the app is opened after being closed for many hours, after being closed the night before, or when its open and no streaming has occured for many hours.
1 tap to open Sonos App on my iPhone 7plus (latest upgrade for both)
2 app opens to My Sonos but the main screen is grayed out and each item that is greyed out is flashing.
My Sonos is set with Recently Played then Stations (there are others but those are the only two visible when opening the app).
3 if i click on <rooms> or <browse> then back to <My Sonos> then the flashing is stopped and the items show instead of being greyed out.
4 as long as I keep it open for that priod of use it will be fine
5 sometimes if its been open for hours and not used (nothing streaming). then when tap or switch to it, the same behaviour happens.
and yes i have uninstalled and reinstalled several times. no change
