I'm having this issue. Device#1 sends updated data to iCloud fine, but Device#2 doesn't get notified of changes consistently. Sometimes it happens, but often it does not.

I’m also building a health app. How do I handle a situation where the user doesn’t want to grant Health access, but I want my app to be able to still function using local data via SwiftData? How would these two data stores coexist if the user later grants health access?
