Thank you for your question.
This page or other popups are appearing after a free session and can not be turned off. Only connections in which (at least) one side of the connection has a valid TeamViewer license won´t get this site or other popups.
I hope the info helps you,
Thank you for your answer. It is extremely frustrating to have to deal with this, I use a program to automise certain tasks (on a video game) and when the chrome window pops up, my automatic program that plays for me on the video game will not work. I had to use a line of code that will detect if chrome is open or not, and shut down chrome is it opens up.
If anyone is interested I can share my .exe file that does this.
