Good building assistant, but, and there's always a but. Color saturation is bad. White or clear, I spent a good 20 mins looking for a 1x1 white block. When I was about to file a missing piece, I came across a clear 1x1 block. Same issues with black and charcoal (dark grey). It's not as bad as the white, clear, but needed to say again. Needless to say, it can't replace the books that come with it

UPDATE 1/12/25-I posted a review about lingering builds that won't clear. I tried to use the reset button but it didn't seem to work. Marine, from LEGO CS, mentioned it in her response, I tried again & it worked. Thank You Marine! However, there is a lingering issue with the app just crashing & my tablet is compatible. Outside of that, I enjoy the app & ease of use with instructions (pdf & 3d), although 3D needs options like stop animation, better skip or pages for quick access. Was 3.5 stars :)

Thanks for taking the time to share this feedback with us! We'd love to hear more about your experience via LEGO.build/Service-GPlay, so we can gather more information. In the meantime, you can click on "Reset building progress" on any set's page to have them disappear from the "continue building" section. 📲 - Marine, LEGO® Customer Service

It was exciting to see an update available. I thought: "Awesome, they surely fixed the age check math quiz and I'll be able to register sets again." Nope, not fixed. What is so difficult about fixing this bug? Why not just roll back to a previous version? This app has two primary purposes, and one of them is completely broken. Embarrassing.

This isn't the experience we want for our fans and can totally understand the frustration! We'd love to hear more via LEGO.build/Service-GPlay so we can investigate the issue further. - Marine, LEGO® Customer Service
