I have tried on two different devices and three separate browsers, including edge, and I have not been able to log into the Minecraft Feedback forum. It'll redirect me to a Microsoft login page, I'll provide the proper credentials, and then it'll tell me it's logging me out every time. Which is really frustrating. I know it's not a problem with my account, as I'm obviously posting using said account, and I can log in everywhere else, but as soon as I open the Minecraft Feedback forum, it'll require me to log in (even if I'm already logged into Microsoft elsewhere), and then the same thing happens over and over. I've seen posts about this on the Minecraft Bug Reporter, but I figured I'd let the source know.
