@MojangSupport Is the login servers down or something? I cannot log into any of my Minecraft accounts... it just tells me i need to purchase and will not let me do anything but play the demo, but I have already purchased the game on all of my accounts :(

I migrated my account to Microsoft a long time ago and today I have exactly the same problem @MojangSupport

It seems to only affect the MultiMC for me with the regular launcher it works for me.

same i also use multimc but minecraft.net is also down and also this
