No, Never heard of that.
You can check when they will shutdown the server via this link:

However, UBI may ship a feature-missing product and discontinue the service before they fixed the feature.
Just Dance 2016 (PS3/XBOX 360) was claimed to have "VIP dance mode", which is an old mode inherited from JD2015.
However, the "VIP mode" has NEVER been implemented in JD2016.
Nov/11/2018, UBI closed the server for JD2016 (PS3/XBOX 360), before they tried to fix this missing feature.
Everybody should know those nasty behaviors of UBISOFT.
And now, I will tell you, UBISOFT is still not shipping the "BOSS Fight" Feature in Just Dance 2020.
Guess what, we will see.
