Hi, app is great and very helpful however there is one thing I would be happy to have in it - could you please add the mark for every set to show if it is owned or not - It would be much easier to plan future purchases.

Bug in LEGO Builder – First Sets Disappear and replace After Adding 1000th Set or more

Hello, LEGO Builder developers,I can't save more than 1000 instructions, after trying to save, the instructions are replaced and those that were added earlier disappear. I am certainly grateful that now there are not 755 like before, but 1000 is not enough for me as a collector, only the city collection has 660 sets, as well as about 300 star wars, and 10 other series that I can't add because there is not enough space, I am forced to choose a priority.

Thank you for your feedback! We’ve shared it with our developers for a closer look. We understand how important it is for you to see your entire collection, and we're working on a fix. Stay tuned for updates! 👀🛠️ - Mathieu, LEGO® Customer Service

App looks nice. The only thing I do not like - if minimize the app while instructions are opened. If i open app again in a minute or later - app relaunch to initial screen. And moreover app randomly remember what sets was opened in this case, so it’s pretty often I have to manually search again and again the same set because i do not see it in Continue Building :(This is a bug or feature? If the last - well, it’s very frustrating…
