I've had this issue for the last couple of builds. I'm currently running Patch 5 build 1460. Has anyone else experienced the same? What I see (If I look really hard) is that the search results queried via the URI bar start to load, but then the page almost instantly reloads to a blank Google search page. This is a pretty crippling UX bug.
Chrome only. SAE extension works fine for IE on the same laptops I tired (haven't tested Firefox). I keep Chrome up to date, and it's been happening for the past month at least (not sure which version it started with, but it persists in 55.0.2883.87).
