Hiya, is it your language settings? You need to go into your profile Settings, scroll down until you see Languages (not interface language). Make sure you have Undetermined AND English selected, as well as any other languages that you want to see. To select multiple languages, hold down ctrl on PC, cmd on Mac, or tick the ones you want on the list on a mobile browser. Hopefully when you've selected English, the rest of the posts will show up :)
