Yeah, it's still being weird today. Just really sluggish scrolling around and searching for things. Also I noticed that the Chrome tab for Watch2Gether keeps loading. The little 'spinning loading' symbol shows up occasionally even when I'm not using it or anything happening in the room.
Maybe that's normal and I'm just noticing it now? Performance does seem better in incognito mode.. Still a little sluggish, but not nearly as bad as without Icognito mode.
