Calendars on iPod sync erratically with calendars on iMac. Updated to iOS9 3 days ago -- changes to calendars on iMac have synced three times (3 times!) to calendars on iPod.
Mysteriously:
(1) MLB calendar still updates automatically, as quickly as before the iOS9 update.
(2) Changes to iPod calendars appear on iMac calendars as quickly as before the iOS9 update.
