You do not have permission to post to this room -> in rooms that I can write to from the discord app

Hi all,

I have a weird issue, there are rooms that says, "You do not have permission to post to this room" even though, I can write to them from the corresponding discord room. I use the "Linking your discord account" method, Friend management is not enabled, but autoinvite is enabled. I installed the bridge via, Slavi's ansible playbook. I have this in the inventory file:

matrix_mx_puppet_discord_enabled: true
matrix_mx_puppet_discord_configuration_extension_yaml: {namePatterns: {user: ":name (Discord)", userOverride: ":displayname (:name)", room: ":name", group: ":name"}}

What information do you require to help solving this issue? I appreciate your help! Best regards, Gergely
