Right after midnight 1 Jan 2022, I started missing the icons that should be shown on the first swipe from the top edge down. Tapping the places where I’d expect the icons performs the expected action (i.e. wifi turns on/off). But the images are gone. I tried restarting the phone and that did not help.
Maybe rearrange the icons, and save it. Or add some icons if you just have few - if you have many, take some away. That saving could help the system to load it.
FP support contacted me offering to exchange the phone for me. As I would anyways put it into factory defaults, I did so now, and it fixed the issue. I hope it will not pop up again.
