can't upload appxupload file to microsoft store RRS feed

  • Question

  •  hi,

    I am trying to deploy a new version of our UWP app
    I am the doing the following steps:
    1. in my store account, I open a new submission.
    2. under  "packages" I upload my new appxupload file

    after a second, I see "error" displayed near the progress bar.
    after refreshing the page, I see the following list of errors:

    The package RestQ.Universal_4.21.2.0_x86_x64_bundle.appxupload is taking a long time to process. If this isn’t completed soon, try refreshing the page, or remove the package and then upload it again. If you continue to see this issue, contact support.
    You must fix all package validation errors before submitting.

    your assistance is much appreciated,
