Sometime since July 2024 the list of devices in our Enterprise Account is showing the same device and UDID 6 times.
Looking at the DATE REGISTERED field it is apparent that each instance of the device represents the 'old' device that should have been 'deleted' when the annual device reset was actioned. The date registered field shows dates with 2019, 2020, 2021, and so till 2024 (most recent).
I have 'disabled' two of the entries to see what happens, and those instances were disabled as expected without impacting the other instances. However, when attempting a re-enable of them, an error throws saying that they cant be enabled because that UDID already exists - obviously the other instances.
For now, I have left 4 active duplicates in place, and the 2 disabled ones as they are, and plan to deal with this again - if it re-occurs in 2025.
It does not seem to have impacted provisioing profiles - so will leave well enough alone. I am sure if I disable all of them, I will not be able to re-enabled any of them.
Is this a know issue? Is this the best strategy? - ie, wait till device reset next year and hope issue is resolved.
