Upload UWP App to Microsoft Store has validation error

Question

I tried to upload my .appxupload file to Submission in Microsoft Store, but I got this message:

Package acceptance validation error: The package file format for LoginNavigation.UWP_1.0.143.0_x86_x64_arm.appxbundle is invalid: Retrieving the COM class factory for component with CLSID {378E0446-5384-43B7-8877-E7DBDD883446} failed due to the following error: 800b0101 A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file. (Exception from HRESULT: 0x800B0101).. Update the package and try again.

I built Xamarin App with: Microsoft Visual Studio Community 2019 Version 16.7.0

Does anybody has the same Problem ?

Thanks

Answer 1

My upload finally went through. I didn't do anything special. I deleted the failed package and re-uploaded the exact same .appxupload file.

Either I got lucky, or the underlying issue was corrected.

Answer 2

I'm getting this with a Native Windows 10 UWP app submission.

"Package acceptance validation error: The package file format for (AppBunbleName).appxbundle is invalid: Retrieving the COM class factory for component with CLSID {(app's guid)} failed due to the following error: 800b0101 A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file. (Exception from HRESULT: 0x800B0101).. Update the package and try again."

with an app that worked fine submitting yesterday.

We have a major release that has been over 1 year in the making scheduled for release today.

Answer 3

Package submissions seemed to start working again correctly after 12PM PST, 11th of August 2020. Also the package was created with Visual Studio 16.7.1 which released this morning, but not sure if that made a difference. Seems to be hit and miss though, keep trying.

Look for the GREATLY improved Notebook Pro 2.4 later today!!

Answer 4

Hello,

Welcome to Microsoft Q&A!

The issue has been fixed. The app submission could work now.

Besides, currently, submitting and publishing apps is not supported in Microsoft Q&A. Please ask questions about submitting and publishing in Submitting and Publishing Apps forum.

Thank you.
