Any experience using EASY EDA on smart phone?

Yesterday I could manage to run it by positioning the phone on desktop mode. I stated the schematic with some difficulty of a novice but I could do something. Today I want to continue, the screen doesn't show the canvas except for very short instant when I switch to mobile mode.
Any ideas how I can fix it?
 
By manipulating randomly this that, I could make it work. Here how it does. First must start design mode with the phone on desktop mode (3 verical dots on the upper right of the screen to scroll) need to modify the opened file and switch back from desktop to mobile mode. The EDA will ask to cancel or leave, choose cancel and you have the working screen in mobile mode. Or else it will switch to EDITER MOBILE and you get rudimentary screen.
Now I need to find the simplest modification to apply on the opened file where nothing is visible.
I just right clicked the "sheet1" and modify then switch to mobile mode.
