Bizarre streamer behaviour

Just had a power cut. Power back on and my ND5XS2 now has the small light indicator next to the power button continuously flashing red.
Audio is behaving perfectly well.
When I go to settings on the app, I get the image I’ve attached.
Is there some sort of update going on?

The image just shows a menu, so doesn’t really tell you anything. If you go into System Settings > Check for Updates it will tell you if one is available, but if it’s in progress, a) you should know, as you would need to have initiated the process, and b) the streamer would normally disappear from the app until the update was complete.

Ta. Powered the box down completely then re-connected.

All good.
