PWA Package Identity Mismatch Error - Cannot Upload to Windows Store

I am trying to upload a PWA app to the Windows Store but encountering package identity validation errors.

App Information:

• App Name: 治愈每一天 (Healing Every Day)
• Store ID: 9NRHKL73J20K
• Product Type: MSIX or PWA app

Problem:

I used PWA Builder (pwabuilder.com) to generate a Windows package with the exact identity information from my Partner Center Product Identity page:

• Package ID: DailyQuoteStudio.608764DDCEAA
• Publisher: CN=A6FB4113-0AE0-4486-8B28-2D5BEBD01DC9
• Publisher Display Name: Daily Quote Studio

However, when uploading the .msixbundle file to Partner Center, I get validation errors saying the package identity doesn't match. The error shows a different Package Family Name suffix than what's displayed in my Product Identity page.

Steps Already Tried:

1. Verified all identity information matches Product Identity page
2. Regenerated package multiple times
3. Deleted and recreated the app
4. Double-checked Publisher ID (A6FB4113, not A6F8)

Question:

How can I resolve this identity mismatch? Should I reset my app's identity or use a different method to generate the package?

Thank you!
