Bring the old app back!!!

We bought both of the old train sets and now poof, no app. Just bring it back please. My kids and I are very disappointed.

Whose Decision Was It To Change The App?!?!!

The new app is ridiculous. My son has the older model and it’s his favorite. He doesn’t want the newer version and he hates the updated app. If it’s not broke, there is no need to fix it and there was no need to change the app. It was much more engaging with a better variety of activities and controls. Everything everyone else is saying is absolutely true. This has been a huge disappointment for my kiddo and my pockets. If I pay for an item, I expect to be able to utilize it entirely and to its fullest capability. It’s a little insulting that you’ve removed that option after already receiving full price. Would it have been impossible to keep the old app available as well? Lego…do better!

Leider wirklich schlecht

Ich verstehe es nicht, die alte App war nicht perfekt, aber die neue ist ein absolutes Downgrade.
So wird ein glücklicherweise haltbares Spielzeug per Software künstlich nutzlos gemacht.

Terrible update loss of experience

Absolutely horrible update for this train set. It has made it a really poor playing experience for the old red trains with lack of interactive buttons, speed control, action blocks. Seriously bring back the old app.
