Are your tickets part of a package? If so, this is what you will see until the exact moment that your booking window opens.
Thanks for the response, but it was a glitch with the app. And happened again when I was 95% done booking my FPs. (That was incredibly stressful when, after over an hour and a half of work, all of my listed FP plans showed that I only had a party of 1 instead of 7 for each! I had to call and verify with a CM that there were really FPs for everyone in my party.)
The tickets for half were purchased separately and linked; the others had APs. I could see the ticket info and everyone on my computer but not on the app.
The issue was that it wasn’t showing me anyone in my actual party (my children and parents) for this trip, but it did list other “friends and family” under the “Add guest” section. So it was obviously pulling some info, just not including the people I needed.
