Almost found a solution this morning that may or may not help others....
Some posts are recommended ding setting up the HomeKit area, of course for those that have never done this it could be the solution. For others, I'm sure they have already set up HomeKit before Fitness+ even came out so not much to see here.
Then there are posts about making sure you have iCloud set up as well. Again for those that have never done this it could be path to getting things to work.
This morning went to one of my ATV gen4 and
- Logged it out of iCloud under accounts
- restrated
- Logged back into my iCloud account
- The above process obviously removed ATV form HomeKit as well.
- I now saw the red 1 more thing to configure inside the AirPlay HomeKit section; my hopes were high
- Went into Airplay/HomeKit section and was prompted to connect phone (bring it by ATV, bluetooth, etc)
- Set everything up; and still a no go for my watch
- Restarted; no go
- Went back to HomeKit changed name of room device was in; no go
- Changed name of device, no go...
- Again, my wife's watch was already working before all this and still worked after I did all above.
I think this is karma for all the times I had upgraded my phone, watch, with new features/emojis and she's like "how do you get that?" and I just replied update your phone fool 🤣
Anyway for some it may help to go through steps above. At this point only thing I have not done is reset phone, watch. Not in mood to go through that yet. Working fine for me with phone, iPad, and watch so I can wait on ATV to; as apple puts it "just work" 🙄
