I'm having the same problem
I was hoping, since this thread was older, there'd be some help. I'm forever stuck at 13 machine rewards whenever I start my game, never getting the all machine rewards achievement, even though I've bought them all several times. I am also frozen on 3 stickers needed for one of my last 3 aliases. If I look at the pages, it shows the several missing every time I start the game. I am a level 133 and never received the achievement for reaching level 100. I'm also stuck with two more locked aliases 39/40 just dance songs and 45/52. I've danced to all of them many times. I only have xbox 1 so the reasoning about the multiple consoles isn't accurate. I really hope they fix this...
playstation and switch account problem
My son played just dance 2021 for last 6 months on playstation 4. Then I bought a nintendo switch and logged into my ubisoft account on the switch. He played just dance on the switch. This broke the last two trophies he needs to "finish" the rewards - he had a few gift machines to unlock and then would have gotten the platinum achievement. However, i think he got a couple gift machine rewards on the nintendo switch, and even though it shows that he has won all 306 rewards, it did not unlock the ps trophies. how can i get this resolved. My son is very disappointed after spending so long working on this game.
