I’ve used “Find My” on my iPhone for a long time to keep track of family devices, including to check up on kids (one with iPhone, one with an Apple Watch). I just upgraded one kid from the watch to a new phone, and we had some issues, so Apple CS did some troubleshooting with me and had me update my OS to 17.3.1 from whatever old version I was running (I’m intentionally a very late adopter with any OS). We seemed to have sorted out all of the increasingly complex settings including all the Parental Controls, but I’ve noticed that the Find My is very, very slow to update now. For example, we use Find My to see if the kids are still at practice / game or if they are on their way home. When it was the latter, we could actually watch their little user icon moving through the map in real time. Since the update though, the icons not only don’t move anymore, they only seem to update every so often. We were testing the new phone yesterday, and it showed the location as not having changed from being at school to being at home a good 5 minutes after my daughter had already arrived at home. So that was probably 20 minutes in between updates.
Other than the hardware addition, and the software update, there has been no changes to anything obvious in this situation to explain the change in behavior. Has anyone else noticed this? Or maybe I’m all of a sudden doing something incorrectly? Obviously if there is a 20 minute update delay in Find My, the utility of this application is greatly reduced.
