Cannot upload to mblock 5 with light & sound extension

#1

I just began using this. I can update firmware and upload my own code. But when I select items from the mbot light and sound extension it continuously gives an error. I have tried this using mblock 5 web, mblock 5 windows and mblock 5 android. It does not work on any

That is strange. Will you take any screen shots for video? And restart your software and try again? I tested and it works in my side.
