The ms-appinstaller protocol has been disabled.
I just found out that users can no longer install my MSIX from my website. This is a WPF application packaged with "Windows Application Packaging Project" (wapproj). When users click the "Get the app" button they now see the error below saying the protocol has been disabled. Why is this? Is this permanent? Is there a way to enable it?
There's a short mention of this in the docs but it doesn't mention why this is happening or how to enable it.

The ms-appinstaller protocol has been disabled. Please ask the vendor to update the weblink. For more information go to aka.ms/ms-appinstaller-disabled
bvenhaus Thank you for your question. We removed the ms-appinstaller custom scheme due to a security vulnerability. We do intend to bring this back, and are working on it. For now, you can update the link on your website by removing 'ms-appinstaller:?source='
