If I have notifications for an app, Twitter for example, in the Notification Center and click on one. When I go back to the Notification Center all the Twitter notifications are gone. It's not just Twitter. It's any app. Anyone else?
Yeah it's pretty much the way it was but has changed in iOS 10 now there not lumped together like before and only the Notification you tap on disappears
No. I'm on iOS 10. All notifications for Twitter disappear when I click on one. Basically going into an app off one of the notifications makes all the others for that particular app disappear.
Developers have control over how notifications are added/removed in Notification Center. Twitter chooses to remove them all when you tap on any of them.
