My new iPhone SE often won't update Notes
We keep our grocery list in a Note shared among Notes on iCloud, an iPad, an iPhone 6, an iPhone 5c, A 2009 MacBook Pro running El Capitan, a 2015 MacBook Pro running Mojave, and a (new) iPhone SE. All sync flawlessly with each other EXCEPT my iPhone SE does not update the grocery list very often. When I touch that little sharing icon second-from-the-right-at-the-top-of-the-Notes, the iPhone screen flashes and produces an alert:
Couldn't Connect
There may be a problem
with the server. Please try
again later.
The odd thing is, that my iPhone SE DOES update now and then, when I'm not looking. Also, updates entered on my iPhone SE propagate to our other devices pretty quickly.
Any ideas how to research what's happening here?
