I try to edit the automatically generated file AppxManifest.xml (removing the "Capabilities" section from it, or completely replacing its contents with a standard pattern from RAD Studio help), change the manifest file name and specify the manifest setting as "Custom". Still, the result is the same: Microsoft Store doesn't like the line about "restricted capabilities", though now this line isn't supposed to be there at all.
It really looks like an appx file always contains a standard, automatically generated manifest, even when I try to specify it in my own way.
it's Microsoft procedure issue. I make my Delphi application to be available on Microsoft Store for 3 weeks.
If you generate appx from Embarcadero products its working fine. First at all (after you have create developer account, pay money and create application record in developer center) you need to submit on that page
to get permissions from Microsoft (you need some data from developer center and application) - its not automated, it will be done by people. After that You will be asked to download yours application in some other special place (Microsoft help upload). People from Microsoft will check it. After you get all issue verified and , you will be able to download to Microsoft Store ;-(
