Hopefully someone sees this even though it was a few months ago.. I've spent probably 10 hours on the phone now trying to fix this same problem.. I have uninstalled the app many many times, logged in and out many times in all of the ways detailed here, including from a computer, and nothing works. EVERY single time I call Princess I get an out of country (Philippines) help desk that has no idea how to fix these issues (unable to enter info when I try to go ocean ready, correct page pops up briefly, sometimes get to enter info, and I get "this booking has already been claimed" etc etc..) and they won't give me a phone number for the "Medallion Desk," my cruise consultant keeps telling me to call. I call customer service (not my CC) and ask to be transferred to the Medallion Desk, and I end up out of country again.
I've been told this happens when you use the same address, phone number, and email for the second guest in the cabin. All of those things were fixed.
***Does anyone have the direct number to Princess IT?!!*** As in the real Medallion Desk? I have tried every phone tree option, and it seems to be impossible. I'm not worried about getting on the ship, but I want to use the damn app once I'm onboard!
Thank you!
