google keep

I used to use Google Keep. In my recent move to Apple System, my wife and I moved to Apple Notes for our shopping list and other stuff. Google Keep, used to have a feature in lists when you start typing in a list item, that is already in the list, for example, I type Bread, it's on the list...

iOS 10.1.1 iPad Air (cellular) & iPhone 6s+ I make notes in the Apple Notes app on my iPad, and they don't show up on my phone, even days later. I have all iCloud options turned on, on both devices. What am I doing wrong? On the same devices, Google Keep syncs almost instantaneously.
