Xbox Series X & Astro HDMI Adapter help

I received my adapter today but am having issues getting the adapter to run on the settings I want. I am using an ASUS VG27AQ and play @ 1440p/120hz for games like COD. When the adapter is connected it removes the ability to set the refresh rate for any resolution including 1440p/1080p. Astro confirmed that 120hz is supported and all my equipment matches the requirements as stated on the Astro Blog.

Has anyone been able to successfully enable this via the Xbox settings?
