I can see them on the web version when I 'check' the box, and I can see them on the iPhone Calendar LISTS option when I edit the search criteria - is there a way to show ALL PROJECT events on the actual Calendar view on iPhone?
If you turn on the All Projects filter from the events list, then click the search button to close the filters, that saves the filters and they will be used when you view the calendar.
Yep, that got it. Many thanks.
