Unusual UDID using my Apple Music
I have had some unusual activity in my Apple Music so I downloaded my data. I can see my device (device identifier/UDID is 00008XXX-001A20AAXXXXXXXX) but also a device with a UDID format I don't understand:
AaWfNSvkyXXXX/HzGaYq6BO8VF4xXMF4fC8uR/XXXXXX
(Xs to de-identify)
It's apparently an iPhone 11.
Can anyone explain this UDID format to me?
iPhone 11, iOS 17
