It appears there's an issue with the Mac App Store's ability to process offer codes, unlike its iOS counterpart, which handles them seamlessly. Users attempting to redeem a code on their Mac are encountering a "Cannot redeem code. Try another code" error.
Considering the Mac App Store's long history, having been introduced nearly 13 years ago, it's high time for it to align with the iOS App Store's functionality. While it's close to 80% there, addressing these lingering issues would greatly improve the user experience.
