Thank you page not displaying at the end of the purchase process.

Hi,
I am currently using the free version to make sure I’m happy with how it works/looks/functions etc and am considering purchasing the pro version.

Everything works great, until I go through the purchase process (I’m running in test mode as my site is not yet live), and the Villatheme thank you page is not the one that’s displayed – it’s the default thank you page.

Is there something I’ve missed with the set up as I can’t see anywhere in the documentation to say that we have to point this page to the Villatheme thank you page, and I can’t even see a created Villatheme thank you page in my ‘Pages’ section.

The reason I ask this is because if it’s due to my theme (Astra Pro) or something and it doesn’t work with pro, there’s no point me buying something that won’t work.

Any ideas on what I should be looking for?
Thank so much.
