App once again does not work & has not been working propperly ever since they added the random course stuff. Mario & Luigi need updating to play with the sets but as the app doesnt launch & sits in a blue screen with 2 white boxes i cannot use the sets or play with the product. Lego is an amazing toy company but has & clearly always will be one of the worst when it comes to apps as they never work & always have issues. This is what happens when you try to force gimmicks on toys
