What I have done so far:
- removed the server calendar from the iPad by deleting the relevant account
- removed subscribed calendars from the iPad
Result: no entries in either the iPad's calendar and reminders
Then i switched off the calendar service on the server itself and rebooted the same.
Then I switched the calendar service on again
At this point in time calendar and reminder entries are all o.k. on my iMac, MacBook and iPhone and entries
made on one of them are showing up correctly on all the other devices
( Note: I am using on all devices the same account in the calendar account set-up ).
Next:
- rebooted the iPad
- entered the server calendar account again and made sure that both Calendar and reminders are switched on
(Note: I made sure that the set-up on my two iOS 8.1 devices ( iPad and iPhone ) are 100% the same for the calendar account )
- after a little while: iPad > reminders are showing 100% correct
> only a handful of entries for the current month are shown in the iPad calendar. Same after another hours wait.
I checked the Server calendar logs but they look normal.
