AptX Audio Codecs on X Elite Linup

Recently purchased the Sennheiser Momentum 4 and have been loving them. I also upgraded my Surface Pro 7 to the new Surface Pro 11 with the Qualcomm X Elite Chip. I was really excited because the chip supports the AptX Adaptive audio codec which is what the Momentum 4 uses for high quality audio, but when I tried it out today I'm only getting the AAC Codec (much lower quality).

Is this just a Windows issue? Will AptX support be coming in a future update? It would be really frustrating to not be able to listen to high quality playback because of a software issue
