IOS 10.1 Beta My Mac and iCloud Calendars (checked on webpage) are updating and syncing though not my iPhone. I have closed down the Calendar app and done a hard reset a few times to no avail. In settings Calendar is ticked to sync in iCloud. Since last night ! Any ideas ? Thanks in advance. --- Post Merged, Sep 27, 2016 --- Sorted by signing out of iCloud then back in. Initially removed all iCloud data during the process.
