So my iPhone no issues, with regards to my spouse, had issues so just now deleted the geofence variable in the ISY, and setup a new variable on the phone syc'd to the ISY, fingers crossed... Her phone was untouched and never upgraded to IOS 15 until 2 days ago so probably why I had to do this. With myself I had done these steps when trouble shooting why the geofencing was not working during the upgrades of IOS 15..
Keep you posted, but it looks like the above is necessary...
