Webviewer stops to work (cant be scrolled)when screen orientation of phone changed or advertisement ends

hello everyone,
I have created a new application in kodular where i used an web viewer . but my problem is that whenever an advertisement showed or screen orientation changed while webviewer is opened after the orientation changed or advertisement ends the web viewr is paused and it cannot be scrolled up & down.

So I am here to share my problem. if there is anyone who helped me out of this problem.
please share your experience.
thanking you all.
