Hi Sheena
Thanks for contacting us.
Yes, you can edit this theme with the Elemnetor page builder. but you cannot edit the default homepage with the elementor. because it is a default part of the Aasta Pro theme so this is not editable.
In fact, Using this Aasta Pro theme you can create, edit, and update page designs as per the requirement. That is why we have made this theme fully compatible with Elementar Page Builder.
But the default pages of the theme are not editable with the Elementor page builder.
We hope your confusion is cleared.
Thanks
