Notifications become invisible
Sometimes when i receive a notification, i see it, then when i lock and unlock, theres is still a gap as big as the notification was but the notification itself is invisible. I cant tap on it to open. when i get a new notification, and the other invisible one moves down below the „notification center“ line, the invisible notification becomes visible again. My system is up to date, i have an iphone 11. how can i fix this? Thanks!
