For in-game recentering, press the Xbox button and choose the re-center option on the right hand icons. For recentering Home itself, open the Oculus desktop app and choose the gear icon on top right -> Settings -> Devices -> Sensor -> Setup Sensor and follow the directions.
Can we get this with in home as well? Took me a while to search for the fix. I think it be better to just have a option under the re-center option instead even if it's the same as going through the gear.
