I've been trying to access HiFi for the past week or so, I sent an email to support as well. Every time I load into a world, it loads the content fully and then moments later unloads and reloads only partially. People are gray spheres and I can only move about via teleporting. I sent a speed test showing that I'm running around 450-500mbps down and 330mbps up. I have no other issues with other online games including social VR apps like VRChat, and I'm running on a GTX 1060 with a Ryzen 7 2700x. This occurs on both the Oculus and Steam clients. My DNS is set to 22.214.171.124.
