Would not be the first time there was a link to a non working feature on MDEThat makes sense. Assigning a renewal to someone who doesn't have an annual pass would just be a way for the someone to get a discount on a new pass and that is not Disney's intent.
you can reassign unactivated AP vouchers and tickets. While technically the renewal is unused till you enter the park with it again it is not inactivated. The use start date picks right up day after the other one’s last use date no matter when you use it next. So it always belongs to the same user
I move the vouchers around often
for whatever reason to MDE they look the same so they both get reassign link even though you can’t do it to renewals
