Background photo randomly disappears.
I have been having a weird problem for the past few weeks. I have iphone 13 pro max with latest ios 16.2. At random times my lock screen and home screen background picture will disappear and leave a blank background. I can go to settings and the picture appears, but will not actually display as the background. I can change it, and change back, changing will allow the new image to appear, but changing back goes blank again. If I restart phone, then it gets temporarily fixed, but will eventually randomly go blank again.
