As in topic...
When I long press on the notification i see 'Screenshot status" (or smth similar, my system is not in english) from system app "System UI", with info: those notifications can't be modified.
When I press cog icon I can see notification settings for this app (System UI), with a lot of different notification types, that... can't be changes, as they are grayed out... Only 2 out of 20 can be changed...
So... any way to make them not grayed out?
