Great app! very helpful and when available I prefer the 3D instructions over the paper ones. As a suggestion I wish I could mark missing pieces and have ordering and more filter options. Currently the "scroll right to find set" filter is a bit tedious + sets are shown in registering order when one might want to look at them in number or release order. also, please add an option to manually add more than 1 copy of a set. Scanning allowed you to do that.

I love the app, being able to assemble your collection and have access to old instruction manuals! However.. 1) Not all old sets are available 2) Some sets can be found, but not actually added to the collection 3) The thumbnails load very inconsistently, leaving large visual gaps when viewing the collection, ruining the experience for me. :/ 4) A lot of collections are incomplete, the set can be found individually, but is not part of the collection it should belong to.

Thanks for taking the time to share your experience with us! We'd love to know more about the issues you encounter with the sets not being able to be added to your collection or collections that are incomplete, and about the visual gaps. You can reach out to us via LEGO.build/Service-GPlay, this will allow us to investigate the issues further. 😊📞

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
