Cannot upload packs, upload/download worlds, or save changes to realms

I cannot upload addons. It says “all done” but when I save changes, it says “check your internet connection and try again”

This happens no matter what addon, device, or network I’ve tried. Wifi, ethernet, mobile data, same thing

I’ve tried replacing the world with one that has the addon already in it but obviously that doesn’t work based on other bug reports
