Can't prepurchase Dragonflight

Hello,

When i try to buy basic Dragonflight expansion, errors pops up saying that I am not eligible with my account. I currently have Shadowlands on that account. Can you please help me with that?

Hey there Frozenheart,

First thing that comes to mind is you may be trying to buy it from the wrong region:
