Realms Plus is expired, even when I have an active monthly subscription

Today the Minecraft bedrock client tells me, that my Realms Plus subscription is expired, and has to be renewed. I have an active monthly subscription which is already payed for, this month (on the 11th of May).

If I click renew Microsoft wants an additional 59 DKK, same if I log out and back in again.

How do you access you Realms Plus server?
