Xbox Game Pass Ultimate Price?

At the moment it's like the Xbox Game Pass Ultimate costs 1 euro per month…

Now I wanted to ask questions because I did not find an answer in the XBox forum…

Do I have to pay 1 euro Euro forever? Or does the price increase after one month? Will the price be higher? I do not want to lose 300 euro from my account just because I do not know xD

Is anyone familiar with it?

You can read it here.

1 euro sign in then 12,99 euro / month.

A Euro permanently would also be ridiculous.

Yes, especially because the other packages would make no sense, since the 1 euro registration cost -.

Thank you.
