I can't post or vote on https://feedback.minecraft.net/hc/en-us. I am logged in ok on https://www.minecraft.net/en-us.

No matter what I do the result is the same - I just get taken to the main feedback home page:

• Click on Login = https://feedback.minecraft.net/hc/en-us/signin?return_to=https%3A%2F%2Ffeedback.minecraft.net%2Fhc%2Fen-us&locale=en-us
• Click vote on a post = https://feedback.minecraft.net/hc/en-us/signin?return_to=https%3A%2F%2Ffeedback.minecraft.net%2Fhc%2Fen-us%2Fcommunity%2Fposts%2F10060906238093-1-20-Jungle-Villagers&locale=en-us
• Click to try and post = https://feedback.minecraft.net/hc/en-us/signin?return_to=https%3A%2F%2Ffeedback.minecraft.net%2Fhc%2Fen-us%2Fcommunity%2Fposts%2Fnew

From these examples I can see there is a "signin?return_to" in the address, so something is tripping up thinking that I am not logged in?

Trying to follow a post (https://feedback.minecraft.net/hc/en-us/community/posts/360047573651-Block-Icon-for-Launcher/subscription.html example) all come back saying that "oops   The page you were looking for doesn't exist   
You may have mistyped the address or the page may have moved"
