One thing I noticed on my Fossil Sport watch was that the first day I went into debugging mode from my
desktop over wifi, I had an IPV4 address.
When finished, I turned off debugging.
Next time I tried to connect to the watch, debugging was only showing IPV6 addresses and there were more than one.
This was somewhat concerning since I don't know what the others are.. possibly my phone but I did not check the mac address at this point.
I did however realize (hoping that turning debug on and off would fix it) that no matter what I did I could not find the IP V4.
Then it dawned on me.
If you just go to wifi and click on your wifi SID under /connectivity/wifi/yourwifi it will show your IP address.
It does not however show your IPV6 address.. go figure.
