I installed the latest update a little over a week ago. Now my calendar keeps messing up. When I add an event a second event duplicating the first shows up a few seconds later. If I delete the extra event, later there will be nothing on the calendar at all. Sometimes events simply disappear, other times they duplicate hours or days later. Is there a fix for this?
Were you using Google?
What Calendar did you have the existing Calendar syncing with.
It seems like you were synced with Google and now both Nook and Google Play Store are trying to synchorinze your calendar.
If you're using Google you could just get the Google Calendar app from Google Play Store.
