I was a happy user of Notifications Off on Android 6.0.
It is an app that lets you block/unblock notifications per app.
On Android 7.1.2 blocking works but unblocking does not work, according to my experience and Play Store reviews.
My question: How to reset notifications, so that all appear?
I tried uninstalling the app, that does not unblock blocked notifications.
Anything easier than reinstalling the OS?
If I knew how Notifications Off works under the hood, I could maybe try to unblock manually?
