Reset your calendar feed

If you  are having trouble with your calendar not syncing properly or you wish to force an update, you can reset your feed.

Note that some calendar applications will reset on their own (Google Calendar, for example, can take up to a day before you see changes), so you may want to wait. But if the problem doesn't clear up, try these steps:

1. Tap Account (bottom right).
2. Select Settings.
3. Tap the Calendar Sync section.
4. Tap Reset Calendar Feed URL.
5. Remove the old calendar feed then re-add the new one.
