I have an issue with my iPhone/Garmin Connect App and a ForeRunner 245M that I no longer use myself.
I've upgraded to a Fenix 7X and have passed on the ForeRunner 245M to my son.
What I've done is unpaired the FR245M from my iPhone 12 Pro from the iOS Bluetooth settings. I have also removed the ForeRunner 245M device from my Garmin Connect Mobile app on my iPhone.
The Fenix 7X has been paired to my iPhone and added to the Garmin Connect Mobile app.
The ForeRunner 245M has been paired to my son's iPhone 7 Plus and added to his Garmin Connect Mobile app on his phone as well.
The issue I have is that when the FR245M is in range of my iPhone 12 Pro, and I have the Garmin Connect Mobile app open, a Bluetooth pairing request pops up from the FR245M, prompting to enter the code displayed on the watch, into the phone. This behavious doesn't happen when I do NOT have the Garmin Connect Mobile app open on my iPhone 12 Pro.
When the Bluetooth pairing prompt appears, I check the Bluetooth devices list in the iOS Bluetooth settings and briefly, the "ForeRunner 245 Music" device appears in that list, but it does not have the litte blue "i"-within-a-circle icon to the right of the entry that allows one to open a sub-menu to allow one to "Forget" the bluetooth device.
Through all this, my new Fenix 7X remains connected to my iPhone, as expected, it being the device most recently paired (over Bluetooth) and added to the Garmin Connect Mobile app.
How do I stop the FR245M from repeatedly trying to re-pair to my iPhone 12Pro? (note that the FR245M is successfully paired to my son's iPhone 7 Plus already)
