If you're seeing an "Invalid" message next to your Apple/iCloud calendar URL, follow these steps to regenerate your calendar URL:
- In iCloud calendar, click on the sharing icon (looks like a wifi icon) next to your calendar name in the left column.
- If "Public Calendar" is checked, uncheck it then click ok.
- Next click on the sharing icon again and check "Public Calendar". This will generate a new URL. Copy and paste this new URL into DAKboard.
