Since I upgraded to Maschine 3, the plugin chain or Insert chain, or whatever it's called, randomly stops working preventing me from adding or removing a plugin. The plus symbol that you click on to add a new plugin disappears. Also, I can no longer switch between groups. I have to restart the program to resolve the problem and then the problem randomly reoccurs. This problem has occurred in every version of Maschine 3. It's seems as if Maschine 3 is broken, at least for me.
