My Original Post
Updated iPad and iPhone 6 to IOS 9.0 (13A344). Running Yosemite on my MPB. I'm not using iDrive just iCloud.
Notes app - changes on the Mac flow to the iPhone & iPad
Cal & Contacts app - changes on the Mac only flow to the iPad
Logging into iCloud web, it shows in the manage under setting - You are running IOS8, Yosemite or newer on these devices. That's strange it knows the MBP is Yosemite but not recognizing the iPhone and iPad as being IOS9.
I couldn't get the download of IOS 9.0.1 to start. I'll try again tomorrow and see if that fixes the problem.
============
update 1:
iCal: If I do a manual sync on the iPhone it will update its calandar with changes made on the MBP cal. If I make a change on the iPhone it will flow to the MBP w/o doing a manual sync on the iPhone. So it seems to be working in 1 direction, iPhone to MBP.
Contacts: although what looks like a sync symbol is on the Contact screen, tapping it does nothing. Still can sync Contacts.
How to manually sync Calendar. 1.) tap on the word Calendar at the bottom of the screen. 2.) on the next screen swipe down, like refreshing you Mail screen.
update 2:
Upgrade to IOS 9.0.1 did not fix the problems. In Settings/iCloud I turned off and on Contacts - nope didn't fix it either. When I turned off, I selected to keep contacts on phone. I was concerned if I delete them, w/ this issue I might not be able to sync them from the Cloud. When turning on it asked if I wanted to Merge, I accepted that - but still not syncing to or from the Cloud.
