I've noticed that https://feedback.minecraft.net/hc/en-us doesn't let you sign in. After clicking the sign in option at the top right of the page it then sends me to Microsoft to sign in. And After that it returns me back to the feedback page only to find that it hasn't actually signed me in. It still says sign in up at the top right.

I also went as far as to changing my password but even that didn't work. I'm at a loss. I've got some amazing ideas that I'd like to share that I hope to potentially some day see added to Minecraft someday.
