Even after updating my iPhone 6, with the latest update, and updating my MacBook Pro with the latest update, I am STILL missing many of my Reminders. I'm trying to narrow the problem down. It appears that I am getting my Reminders onto my iPhone IF I happen to also have my MacBook Pro open (and not in screensaver mode). If my MacBook Pro is in screensaver mode, or if I'm out and about, I'm only getting about half of my Reminders on my iPhone, until I reboot my iPhone....then the rest of them appear. It's not exactly convenient to reboot my iPhone three times a day, JUST to see if I missed any reminders. The same reminders that don't appear on my iPhone, also don't appear on my day job's computer screen, when I am logged into iCloud.com. I used to get pop-up reminders on the tab of my iCloud.com page.
