Does MS Store upgrade appp automatically to mandatory new version?

Question

For UWP windows app registered in MS Store for years.

I submitted new version with marking this version upgrade mandatory.
If a user launches the app in old version, does it automatically upgrade to new version and launch the app again?

I thought this is what it does.
But, recently I submitted new version and tested the upgrade after two days of submission. It launches old version and does NOT upgrade it at all.
Now, I'm confused. Does MS store take care of upgrade or I have to program for upgrade?

Hello,

Welcome to Microsoft Q&A!

Does MS store take care of upgrade or I have to program for upgrade?

You need to write some code in your app to mandatory package updates. The mandatory status of a package update is not enforced by Microsoft, and the OS does not provide a UI to indicate to users that a mandatory app update must be installed. Developers are intended to use the mandatory setting to enforce mandatory app updates in their own code.

You could refer to this document for more information about the code sample: Mandatory package updates.

Thank you.
