What do I need to do to enable stack traces in crash analytics in Microsoft Store?

Question

I have a .NET 8 app packaged with "Windows Application Packaging Project" aka Desktop Bridge and distributed through Microsoft Store.

The .msixupload file contains .appxsym and that file in turn contains a bunch of .pdb files for all bundled projects. So my assumption was that this should be sufficient to see stack traces under https://partner.microsoft.com/en-us/dashboard/insights/analytics/reports/apphealth

However, what I see instead is clr_exception_80131604_companyname.product_product!unknown_function and there's no information where in the app the error occurred.

Is there something else I need to do on my side? Maybe change the type of debug info? Or does apphealth just not support .NET 8 stack traces?
