My son just received the Liebherr R 9800 excavator 42100 LEGO set.
It would seem the Control+ app that is recommended for it simply won't work. It doesn't even connect to the blocks.
What are the available alternatives? And if this SE allows it, any recommendation/comparison between them would be greatly appreciated.
We're just looking to control each motor individually, no fancy achievement, scenarios, etc... We'll be able to compile from source, if needed, on MacOS or Ubuntu. We'll be able to run Android and IOS apps too (although I'd prefer to stick with official app stores), but the house has no Microsoft OSes available.
Edit: apparently control+ Android Pixel 3 simply doesn't work, but the app works on IOS. In my case, using BrickController 2 on Android solved the issue.
