Built-in support for V2 signing for Oculus Quest apps has been making it into new Unity releases for 2019.2, 2019.3, and soon, 2018.4. It shows up as a checkbox in the Player Settings in the Oculus area. We discovered one issue with this in that the change also requires the 1.38.2 version of the ‘Oculus Android’ package. Newly created projects that add Oculus support will automatically get this version of the Oculus Android package. However, existing projects that already had Oculus support set up will not automatically grab the latest version of the package. If you have an existing project and want to use the Quest support, please go to Package Manager (Windows/Package Manager), scroll down to ‘Oculus Android’ and make sure that you’re using the 1.38.2 version of the package. Until you do this, built .apks may be missing some tracking functionality when run on Quest hardware. We’ll look into making sure that future builds of Unity grab the correct version of the package for this change, but until then, doing a quick upgrade in Package Manager should work fine.
