Bug in Fully Kiosk Browser

Since yesterday mit Fully Kiosk Browser app wont close the sidebar/menu.
I cannot close it by hand, nor by remote. Only a restart of the tablet works.
Anyone discovered a similar problem, or knows a solution?

I have the same issue. Any chance someone knows of a solution? Happens every few days and I need to force close the app…

Try to Update everything. My problem was gone at one day and never came back
