Blank page when viewing CRM through Web Application Proxy

I have three instances of Dynamic CRM on-Premises (8.1, 8.2, and 9.0). They're all using the same Server 2019 ADFS server and everything works great internally. They're published to the internet using a Server 2019 WAP. I can even log onto the WAP and pull up the IFD URLs for the CRM servers without any issues. When I hit them externally, I'm properly redirected to the ADFS authentication page where I successfully authenticate. Then I'm redirected back to the original CRM URL I requested, the browser spins for a while and then stops and leaves me with a completely blank page. The tab name updates to "Microsoft Dynamics CRM" and viewing page source does have some content in it. So I know something is being passed.

It seems like CRM doesn't like Windows Server 2019 Web Application Proxy. I know it's not officially supported, but has anyone gotten it to work or know why something simple like a WAP would be incompatible with CRM?

I'm posting this here instead of in another forum because publishing a generic html page works fine externally, so I know the WAP works.

Thanks a lot.
