It's the dashboard bug. If you are shown as partnered under your YouTube channel settings and on Freedom! Dashboard says linked you have nothing to worry about.
As said above. The dashboard is having a bug showing that message. If your youtube channel says it is linked with freedom then you can ignore the message.
Please go to: https://youtube.com/features with the channel that states it is not connected and check that it mentions Freedom! on that page. If it does not then you are currently not partnered and will need to contact the support team to get it sorted.
