Sony Nagara (Xperia 1IV and 5IV) port

A very minor annoyance, but is anyone else finding the Ambience is always reset on reboot? I don’t think it was happenning right from the start, but now it resets to ‘Five’ every time.

I deleted the Five ambience as an experiment, and on restart got a surpringly pleasing plain black background, which I could live with. Going into settings, the Five ambience has reappeared, complete with original background image.

I think I remember the C2 having this issue when first launched - but since the C2 had bigger problems, I don’t remember what happened. I should rummage in the drawer and see if it still happens there, but I think it got fixed?
