FYI: App on iPad suddenly loses colors

[Jedi Tek'Unum]

Latest version of Loxone app and iOS (and Miniserver).

At some point my Loxone app on iPad lost all/(most?) of its colors! It's like it switched into a b/w mode. Restarting app didn't help. Rebooting iPad didn't help. It stayed like this for about a week before...

I finally deleted the app entirely and reinstalled it. Colors back to normal!
