Solution here guys

MN4 Mac to iPad sync issue

So the solution was (assuming you are a max user), export your iPad data to files on iPad create a new data vault on both Mac and iPad, give them same label number import the saved data from iPad This solves the endless downloading of sample study set. Actually their CN forum has way better solution set as well as trouble shooting guide, I used chrome + GPT translator.
