Why doesn't my app's wildcard subdomain work?
Add the root domain to the list of domains in the app’s settings along with the wildcard subdomain.
How do I add an A record to my app on App Platform?

App Platform exposes two static ingress IP addresses that you can use to map A records to your app. These IPs are shared across multiple users and route inbound traffic to the app.
