In https://help.minecraft.net/hc/en-us when I click Java Support it failed to load and then I inspect the page got to the errors and sayd this "Failed to load resource: the server responded with a status of 404 () en-us/categories/360000444511-General:1" then I click the last sentence and says that that page dosent excists.
This is due to the 'Java Support' page still going to the old support website (help.mojang.com). Mojang are aware of this issue and it's on their list to be fixed. (afaik)
