Repeatedly getting "Device Added To Your Account" (or similar) notifications for devices that are already on my account
I have multiple iPhones, iPads, and various Mac computers on my account sharing the same iCloud identity. The iPhones have separate carrier accounts and all of the iPads are also carrier enabled. All of the devices get used due to various dedicated working locations, testing, travel (hotspot, national vs international, etc), workstations in the field, and numerous other situations.
I'm routinely getting notifications for new devices being added, and similar queries, that are already on my network. Worst, the notifications come for each affected service: iCloud account, iMessage, Facetime, etc. I know my situation is somewhat unique being a one-man-operation, but it's still frustrating that I have to keep re-adding the same devices over and over and over again.
It also routinely pops up when I'm in the middle of something time critical and forces me to go through the second factor authentication if I choose Allow.
I understand the intent of this security process for normal users, but would love any input on how to disable or dramatically lengthen these.
