User Profile

In the application I developed, I use the MAC address (RemoteId / UUID) of the bluetooth device I am connecting to as a uniqueId and keep some information and definitions about the device in the database. But as far as I can see, after the last updates, the MAC address that should be fix has been changed. The MAC address of my Bluetooth device in iOS 15 is different, and the MAC address in iOS 16.6 is different. This is causing the problem of not being able to access the information of my Bluetooth device from my application. 1- Why was such a rooted change that would affect all bluetooth devices? 2- What needs to fix this situation. The images below are taken from the bluetooth tool LightBlue.
