Google Calendar does not show any notification in Nexus 7 (2012) and Nexus 5 app, nor on Google Calendar desktop app (Firefox).
Syncing is enabled and the calendar syncs. Under Calendar settings notifications is checked and pop-up notification. Default reminder time is 24 hrs. In the individual all-day events there are 24 hr. reminders and 10 minute reminders. But nothing ever shows anywhere. The screen is unlocked.

Reminders are an important part of a useful calendar. Anyone else have this problem?
