Can't purchase Logic Pro from App Store (May 2023)

I just purchased a new device, namely a Mac mini M2 Pro. I've been trying to buy Logic Pro from the Apple App Store, but every time I click "Buy", there an advice box that says "Purchase of this item is not currently available. This item is being modified. Please try again later."

This has been going on for 2 weeks. I've tried contacting Apple Support, and after a few diagnostic checks, which includes me buying another app (to make sure the issue isn't on my account), they advised me to wait 7-14 days. While this time is now up, there's still no solution and that advice box is still appearing.

Has anyone else faced this issue? Need to hear from other uses if you are facing this issue, and possible solutions.

Thank you!
