Hi there, I' m new to the game. Or well, I would be if this wasn't happening

(in case the image is not seen it says after login: "No testing phase is running at the moment. The next test, the Winter Alpha, is set to start in late February 2021. Keep an eye on our blog,forums...)

So , that means I can't play the alpha and just the beta, and I dont' know how to change it? Or that either of them is open?
I got the pack that's 40 something, that grants you "master" title. That means beta and alpha just open X point in time its servers? Gotta change something?

Thank you
