Companion is blocked when adding side menu.

[connancho (Johan Sneider Ascuntar)]

Hello, I know that there are several users with the same problem, I have read many forums on this problem, and I cannot find the solution …
What happens is that when adding the side menu, the companion begins to present faults and crashes every time a change is made, however small it may be.
Does anybody have any suggestions???

Why my app with 1 screen don´t refresh, it´s close Companion

I have an app with 1 screen + 1 side menu and some vertical arregement. Every time I change something in the Design part, The Companion is closed. So I have to connect it again. In other apps with more than 1 screen, this is done instantly. I change and then a refresh is done and already updates the app. I put another screen (with no function inside it) as a test to test if it would work. Did not work. What can cause this problem? Is there anything I can do to prevent this behavior?
