Waiting for AdSense to start running ads

I’ve had AdSense ads running on my unsecured single page Google domain website for months, but I’m still waiting for ads to start running on my secure multi page WordPress site. My wordpress site receives many more visitors every day than does my Google domain site. I’m missing out on the majority of my potential ad revenue. And by AdSense not approving my WordPress site, Google is missing out on that revenue as well! I was under the impression that once you have and AdSense approved site, it’s simple to add a second.
I guess that’s not the case.
Waiting impatiently.
