Have you abandoned all but the English version?

On the Japanese page this web site appears not to have been updated since 2015. The top of the page is still Halo 5: Guardians, and I can’t even find any mention of Halo Wars 2.
Will it be updated when the time comes for Halo Infinite? Or will it stay like this?

I am experiencing a bug where Halo Waypoint switches languages randomly. I prefer to use the website in English but for some reason, it starts up in German (my native language) despite having my entire PC running in English. I am also making sure that I go on the .com version, not .de. On top of that, I am not even located in Germany right now, so I do not understand how this can be. After a while of use, Waypoint switches to English randomly but often reverts back to German. Another problem aside from the inconvenience is that when I am on the German version rank-up requirements are bugged. According to the German version I need 10 forum posts to rank up again, on the English version it is 25. I believe a solution would be to choose a language preference that would be tied to your profile.
