Ever since building my Lego Grand Piano, I have been going around in circles concerning the power up app. When I activate it, it does not load the sheet music. It works with my Iphone 5, which I took out of storage and my grandsons Iphone11. Both had no issue with the full load. I spent 45 minutes going around in circles with an online chat. I finally gave up and called in. All the person could do is report the issue with no solution.
I am disappointed especially since this is one of Lego's premier products with a $350 price tag.
