Invitation email has bad URL

When user is added and has assigned subscription email is sent. Url in the email has structure : https://xxxxx.developer.azure-api.net/products/productname . After clicking on this url browser is rendering : Page you're looking for doesn't exist.

I guess proper url would be https://xxxxx.developer.azure-api.net/product#product=productname

Start by locating the invitation email URL generation and reproduce the link from the issue in the developer portal. Check the generated route against the expected product URL; done means the invitation link opens the intended product page instead of a missing-page error.
