Unfortunately, you will lose your FPs because Disney is following through on FP Cancellation for FPs booked using onsite reservations that were subsequently canceled.
What you need to do is either delete them now and rebook or wait until the MDX system deletes them and then rebook.
No one has reported deleting and rebooking prior to the system Warning. DISers who received the Warning rebooked after their FPs were deleted.
Thanks for the quick response! It says they’ll be removing them today, is that at midnight or anytime today?
