Hi,
I tried with firefox, edge and Vivaldi, but screen mirror doesn't work here:

• I click on Screen Mirror
• the pop-up appears on my smartphone
• i choose the app to share

...and the browser on my laptop remains blank: completely white.

At the same time, the three buttons (BACK, HOME, ) into the web browser of the laptop that control the same commands of the smartphone DO WORK: if I press the HOME button in my web browser interface, the home is pressed on the smartphone as well, so the connection works, apparently, BUT NOTHING APPEARS ON SCREEN.

Any idea, why that could be?
