Checked and getting the same atm. It's a pretty typical error when something is broken and down temporarily. To make matter worse though I accidentally clicked on the v4.0-Alpha beta test link and I now I'm combing through my profile looking for a way to revert. May just need to reset cookies... I'm sure it's documented somewhere here, but right now everything looks extremely jacked up.I know this is off topic, but can you all access your reactions received and given in your profile? Or do you get this error too? 400 bad requests
