Provide additional instruction if port 8333 confirmed open by third party site but still getting red box "Your IP network is currently pending review."

Could you provide some additional notes to indicate what the next steps should be if we get "Your IP network is currently pending review." when checking our IP?

In my case, I have used canyouseeme.org and confirm that the port is open and listening to on the advertised public IP.

Success: I can see your service on 142.147.58.22 on port (8333)
Your ISP is not blocking port 8333

As a user building my first node, I am keen to make sure I'm all setup for when it finally finishes seeding. If the client is expected to not respond to the crawler until it is fully seeded, a one liner which states that would put our minds at rest.

When the ip/port is publicly accessible and there is a high degree of confidence I don't have any ISP, router or firewall issues. What else should prospective node hosters be checking?
