Did the update but when I tried to use the device, it has become very unstable - shutting down to just the on-screen ‘A’ symbol / dropping WiFi every few seconds. I’ve tried holding the power button down for 10/20 secs etc but no joy. Anyone else finding this? I’m trying to avoid a hard reset because it will mean downloading all my Tidal offline albums again, which I’ve already had to do once in an effort to get Bluetooth to work (the device has never found another device since day one but I’ve lived with it so far). Bluetooth hasn’t worked since the beginning, but everything else was working fine before the FM update. BTW a tangential question: what is the little icon with three upward-arrows and a number underneath? (Top left of home screen, next to the tiny ‘A’. The number underneath changes and the number of arrows highlighted changes as well.) I’ve been through the manual and can’t see a reference to it.
