this is true, I don't know if console users could play with PC users, but I do know that PC users who had the game from microsoft store could still play MP (and mods) with other PC players that used steam/epic... but now you can't because the microsoft store version is not 1.2.8... for whatever reason... was this sort of compatibility even intentional? hopefully its fixed rather than removed.
Afaik xbox got their own vetting process on patches/updates. If TW pushed the update to the platform then it's in the hands of xbox. TW doesn't run xbox after all.
