On the Find My app on my iPhone 12 Pro (latest iOS) I am trying to delete my Home location for a couple of devices (in Notify when Left Behind, Notify Me, Except at) and am getting the error shown in the attachment below. I have tried restarting my iPhone and just been in a call with an Apple engineer (not able to resolve) and issue has been escalated. Has anyone else encountered this issue and if so did you find a solution?
A belated update on this. Apple did fix this issue but did not get back to me to confirm what was the cause. Before the issue was resolved I was getting strange messages related to iCloud so I suspect they deleted a cache or reset something? Anyhow, I subsequently was able to remove locations.
