Video playback might not start when Watch2Gether in a browser tab which is currently in the background and not active.
At the core this behaviour is caused by a browser restriction which limits autoplay in background tabs. Under certain circumstances autoplay might work but it’s hard to get this consistent across all platforms integrated in Watch2Gether.
We are currently evaluating different options to improve this. As a workaround you can run Watch2Gether in it’s own window. This window can be put in the background or being overlapped by other windows and autoplay should still work.
To run Watch2Gether in it’s own window, you can either drag and drop the tab from your browser’s tab menu or select “New Window” in your browser’s main menu.
For Firefox users there is another workaround (advanced users only). Type about:config in your browser’s address bar, search for the setting “media.block-autoplay-until-in-foreground” and set it to “false”.
