Game (on XBox) won't update to 1.18

I have been trying to get my game to update to 1.18 since it dropped. I've tried everything I could find online as well as asked on Reddit and tried all suggested fixes. I've uninstalled/reinstalled too many times to count; I've deleted/reset MAC address; I've deleted all data under MC; and I finally spoke to XBox Support for over an hour and we tried everything they could suggest - including a full factory reset of the console. It still didn't work. Is this happening for anyone else? Is there anything left to try? 

Note - I own the game through Microsoft and I also have access on XBox GamePass. Neither works. I cannot access realms or anything multi-player. I am stuck on version  1.17.1005.70 

Also, the update DOES work for my account when I play on my Nintendo Switch (not sure if this is relevant but adding in case it helps). 

Any and all help would be GREATLY appreciated! Tia
