@Batsudai I fixed it! I went and got an ethernet cable long enough to hardwire my chromecast and voila... Everything works now. Not sure how hardwiring that fixed the controller. But it's working correctly for the first time ever.
same exact problem ... also get controller disconnects sometimes where the linking screen shows back up and then doesn't resolve after doing the linking code, and instead just sits there like I never entered the code at all. The controller vibrates, but that's it.
