Awful experience. As usual all focus seems to be on iPhone. trying to use on my pixel 8 pro and it just refuses to work when trying to build with my girlfriend and our son. Absolute waste of time and energy. constant crashes, UI glitches (White box taking up most of screen that won't disappear and can't Interact with when meant to pass over to someone else) and just non responsive.

That’s definitely not the experience we want for our fans! Since this isn’t a common issue, please try reinstalling the app and restarting your device. If that doesn’t resolve any potential glitches, reach out to our experts at LEGO.build/Service-GPlay so we can take a closer look at the issue. 👀🛠️ - Mathieu, LEGO® Customer Service

I love this app, recently I had a couple of issues. 1 is I use a fold phone and the app can struggle at times and I can't scan barcodes when unfolded and have to reset the app if I fold or unfold so can't qr scan instructions. 2 when using build together the app mixes instructions, this has only been since the last update. over all I love the app

Thanks for taking the time to leave us a review! We'd love to gather more information to understand where these two issues are coming from. Please reach out to our brick experts via LEGO.build/Service-GPlay so we can take a look! - Marine, LEGO® Customer Service

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.
