Many releases ago, probably about 1 year, when I updated an event with an active statusbar notification, your app would remove the notification for that event if I set the new time in the future. This no longer happens. Now, the notification is updated, but instead of being removed, it just shows the new (future) time. Is this a bug or a limitation of your implementation?
I've been using your original Calendar Notifications Plus and also tried this forked version. I'm running AOSP 8.1 on my OnePlus 5.
