When I copied and pasted the Flex Container block twice and then deleted it, there were still 6 fields left in the value selection field. When I tried to change the names of the remaining fields to “Input Float X 1” and “Input Float X 2,” the name of the main container and the nested one changed, not the name of my field. And the preview broke. And is it possible to use a non-beta version for learning? Why is your product testing associated with essentially having to test it, bug after bug? Now I can't even finish the training because everything is broken, and the example needs to be redone by creating a new application.
