I updated two items (secure notes). The changes appeared almost immediately on my home and work computers and on my iPhone (using iCloud sync), but not on my Apple Watch. Hours later, the Watch is still showed the old versions of the Secure Notes.
I was able to force an update of the Secure Notes by opening them on my iPhone, clicking Remove from Apple Watch, then Add to Apple Watch. But shouldn't entries sync to the Watch without this manual intervention?
