advertising on the monitor

I installed CMS version 4 on a server and Android version 4 on a TV box.
It had never happened to me, when I show the layout on the TV box an advertisement pops up on the bottom right and moves the containers further.
Advertising also covers information on television.
Is the problem xibo or the TV box?

Hi and welcome to the community.

Xibo does not have any advertising contained in either the CMS or player software so would check your TV box.

Which TV box do you use?
