Hi there,
Which VR headset do you use?
We've stopped updating the Rift version. So if you want to use SKYBOX Rift version(with AirLink), you can only use v1.1.2 or previous versions.
If you use SKYBOX Quest standalone version, you can update to the latest version 1.1.5. Please check whether you purchased SKYBOX Quest standalone version or Rift version. In other words, please check whether you're in Quest store or Rift store.
Thanks for your understanding and support!
