My SSL is not propagating. Instructions followed exactly. I am seeing multiple threads with people having this same issue, and they are solving it by changing to Cloudflare or similar. I really don't want to do that. I want the tech staff here to jump in and let us know what they are doing to solve this trending issue.

When I first create the custom domain link and get the green check, my site has a valid SSL certificate with the new update, so I know it is being served from the .app location. After about 5 or 10 minutes, the SSL goes away.
