Mac App Store - App Not Available when trying to download

[ghost]

Hi,

I switched to a Mac, and I cannot download from the Mac App Store. I get a prompt saying "App Not Available. This app is currently not available in your country or region". I am based in the UK. I have also tried moving my app store region to US, but I am getting the same prompt. Is there a way to get it back online? Otherwise, can you suggest region(s) where this is available? As long as my employer has an office there, I can use that as a legit address for the Apple ID.

I would rather not play with the SIP, because of the long procedures I would need to go through with my IT department.

Thank you in advance!
