Great App For Certain Sets

First time I used it... wonderful! Colors are a bit off but my son loved playing with it. We decided to buy a small Lego Technic set for my son to use and the app repeatedly won't load the instructions for it. I checked a few more and same thing-some load and some don't. The app says it's not connected to Internet yet all other apps work fine on including two browsers. I deleted and re-installed and experienced same issues. Ate up around 30 minutes of wasted troubleshooting when I could've been playing with my son. He ended up being disappointed as he liked using the app so much the fist time. He finished the set with paper instructions. My point is this: don't make something that doesn't work. You created a need and then failed us. Hope you fix it. I also agree with some of the other comments about limited sets, more or even the whole library would be better. I'd probably even pay for it.

Please update

It would be nice if it was for all Lego sets. Also it would be better if you could download the set instructions instead of being tied to wifi!
