My wife and daughter's NEXUS cards are both expired (5 and 12 months ago, respectively), with renewal application submitted and conditional approval received before expiry. I know their NEXUS cards are usable for at least 5 years after expiry at this point, but I believe the interviews have to be completed within 2 years after conditional approval.

For my wife, I am able to book an appointment at one of the land borders where she can get both US/Canada done at the same point.

In my daughter's account, however, I had previously tried to book the split Canadian interview at YYZ, which I had then cancelled. Now, when I click on book appointment, it kicks me over to the CBSA booking site (i.e. TTP thinks I already have a split Canadian interview booked). Any idea how to cause the TTP site to allow me to book right on the TTP site (i.e. for on the land border locations)?
