Sweet treats showdown failed

I already finished the challenge and received my token but when I tried to spend it, it keeps loading. I closed the app and tried to open it but it came back to where I'm doing the last challenge, I did the same thing that I did to finish the challenge successfully but I failed.  ☹️ It's just so frustrating that I already have 10 tokens for my last royal treat box and that's the last chance for me to be able to get the grandprize but It's gone ☹️
