they don't because pretendo won't add online support for just dance

For now pretendo doesn't support jd online features their are shutdown

Re:squidwardz FALSE! pretendo hasnt confirmed that

Don't know if this will work but for Just Dance 2019 official servers are still available. Dont know how much info the game wants from the account server but if you could set up a plugin that makes the game think it has recived the "Nex service token" then theres a likelihood.

for other just dance games you would need to host your own server. All the just dance games servers are hosted externally by ubisoft, so the games likely already have the server ip adress coded into the game that needs to be changed.

i hope pretendo supports jd in the future
