Detecting Browser Extension

Me and my friend tried to use the extension but it doesnt detect it. This problem only seems to appear on Windows 10, on windows 8 it works normally.

yeah, same hear my girlfriend has a macbook and it is saying to download the extention but she already has it (she uses chrome)

Thanks for your feedback. There was an update today. Please make sure that you use the latest version of the extension 4.3. It should update automatically but you can trigger an update from the extensions settings page as well.

It is on version 4.3.
