The extension is not working for me, but is for my friend

I am unable to share any tabs to my watch2gether room, while my friend has no issues with the extension. Specifically, when I am in the tab I want to share and open the extension menu the share button is greyed out regardless of the tab.
I use Chrome.
I have made sure that my extension is the latest version (version 6.5 at this time), and restarted the browser.
I tried it on Firefox and the same issue happens.
