Hi Angela, and welcome!
You have already done the right thing - informed the schedulers before the shop becomes overdue. Another thing you can do as a safety measure is to enter the shop report and fill out just one answer. That will ensure that the system does not unassign it automatically after midinght of the day of the shop.
So in situations like that, doing those 2 things should work and keep your reports assigned to you until you complete them.
Thanks for asking!
