More than ever lately, I find that zero notification icons show up in my status bar. If I swipe down, I can see a list of all my notifications, but obviously I'd like them to display in the bar.This used to happen very infrequently, and a phone restart would remedy it, and it wouldn't happen again for a long time. It seems even after a restart or powering off, I still have the same issue. I haven't changed any settings either.
What do you see when you click Settings > Notifications > Status Bar ? Is Show Notification Icons turned on? Number of notificaitons?
