Hi,
If I read the post correctly, the direct link provides version 1.0.0 and the Microsoft Store provides version 1.0.1, when the app is installed as version 1.0.0 (from the direct link), the Microsoft Store probes the app as "installed". It seems the Microsoft Store only detects the app, not caring about the version.
The expected behavior is the Microsoft Store showing "not installed" when version 1.0.0 is installed, right? Is this the problem?
Regards,
Alex
