It would be fantastic if my Apple Watch could notify me if my phone is left behind, and use FindMy on my Apple Watch to find my iPhone
Apple Watch Ultra 2, watchOS 11
It already does: Set separation alerts in case you leave a device behind in Find My on iPhone - Apple Support. Then just use Find My in the Apple Watch to locate your iPhone.
I admit I never had the chance to test the functionality on my Apple Watch when I leave my iPhone behind but I can tell you that in my experience with AirTags, when one is left behind, the notification only pops up 5 minutes later. Perhaps it is the same about of time when an iPhone is left behind.
in the Watch app on my iPhone Find My appears to be an app on the watch and it appears notifications are turned on so the Watch should alert me if the iPhone is left behind. However, on the Apple Watch itself, I do not see a FindMy app button. I just tried running an errand leaving the iPhone behind and I got no alerts on my watch.
am I missing something?
I doubt it. I'm not sure what's going on. You could try to unpair and pair again your watch; this can help with pesky issues between iPhone and Apple Watch.
When pairing again, you'll have a choice to restore a backup of the watch. Do this first. If the issue persists, unpair and pair again but choose "as a new watch." You'll loose all your previous settings on the watch but it will be like your watch is brand new to your iPhone, which may clear the issue.
The app on the Apple Watch is actually called "Find Devices", not "Find My". Don't ask me why :)
I see that you participated in this discussion: "Notify When Left Behind" not working on … - Apple Community. The conclusion I draw from it (which might be incorrect) is that the Apple Watch needs a cellular connection to be able to receive a notification. But, somehow, it doesn't make sense; Apple makes no mention of this requirement in the article I cited above.
I thank you for your reply, but FindMy on my Apple Watch is indeed turned on to notify my Apple Watch if separated from my iPhone but it has not worked when needed.
This recent discussion could perhaps interest you: "Notify When Left Behind" not working on … - Apple Community.
EVERY setting is on or activated and I still don’t see a Find My app on my Apple Watch, and today I left the phone home and ran errands for 1/2 hour. There were NO notifications from FindMy on Watch.
