I primarily use my phone for internet through both a WiFi hotspot and tethering on all of my devices, but on the Oculus Quest I can't. I brought this up during one of my Oculus support inquiries, and wasn't exactly given a reason as to why a mobile hotspot isn't supported, even though the hotspots of some smartphones are, as I tested connecting to the WiFi of my brother's phone, and the Quest was able to find it and connect to it without problems. I also don't think that it's a 2.4GHz vs 5GHz problem as I was able to connect both of those on my terribly slow and short range mobile WiFi modem (which also is technically just a smartphone hotspot).
So is there some specific reason? Can I not connect to my phone because it's paired to my Quest for the sake of no extra functionality? I'd like to be able to try out all the online experiences available on the Quest.
