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.

The app was great for tracking our Lego collection, as well as using digital manuals on from the past few years. The bonus points from registering sets are great too. Unfortunately, the latest update has made scanning and registering sets very frustrating. The keyboard entry for the 'adult' maths question either takes ages to register key presses or just plain unresponsive without repeating everything several times. The + button to add sets to the collection is not responding for older sets.

Thanks for your honest review. We're sorry to hear that the app doesn't work the way it should after the latest update. Please try to delete and re-install the app. If that didn't help, get in touch with us at LEGO.build/Service-GPlay, and we'll take a closer look at what's going on! - Sarah, LEGO® Customer Service

Maths question doesn't work if you have just used it. If you open the app for the first time you can scan QR and enter the answer to the maths question. After this though no buttons work on the next maths question. Even after closing the app down and reopening. If I wait a while it will eventually work again. Frustrating as I have about 30 sets to add 😅
