I am using the DUDU7 dedicated device 
13 inches and 250930 version.
I used the hide plugin feature for the first time today and it worked fine.
However, after hiding, when I press the hide plugin button, the plugin does not appear.
Dragging doesn't work and rebooting doesn't show the plugin.
No matter how many times I change the layout settings, the plugin does not appear.
Is there any way to solve this?
