I've tried every combination of rebooting and reintstalling Netflix with no success. I'm pondering just resetting the phone, but I'd rather avoid that simply for one app. With a release coming to the preview ring, I hope that means an update will be coming and maybe applying the update could have the same effect as resetting. I just have no idea why Netflix isn't working. It's a Lumia 950 XL running non-insider builds.
