No play the realms.

Hello, good afternoon, buy a subscription to minecraft realms and when activating realms (image 1) the page redirects me to a blank one, (image 2), then I go to the minecraft game in the latest version (image 3) , I press the realms button and it tells me to buy realms when I already have it purchased (image 4).

Whenever I try to activate it, the page is blank, I have tried it on all my devices and nothing, with which you activate me, it would be the best for me, thanks!
