I contacted Microsoft support via live chat and informed them about the issue.
The support agent mentioned that the app is globally available, but the problem might be related to the timeline for its availability in specific regions. They suggested waiting a couple of days for it to become available in all region.
I checked this thread in the community side, and it seems to be a widespread issue possibly related to specific regions, and both using Windows 11 and 10.
However, since there's no specific information on when it will be available to all, the Microsoft support agent assured me they would inform their superiors about the issue and work towards creating a fix soon.
I hope this information is helpful. I'll continue monitoring the issue on my end and asked the Microsoft agent to inform me whenever there's any update available.
Thank you!
