Mail inbox

I am creating a Facebook account on my new iPhone that is connected to Wi-Fi and has all the permissions granted including the background storage access just to make sure everything goes right and my email has all the permissions granted along with it but for some reason when Facebook sends me a verification email with a verification codeIt doesn’t show up in my inbox and I have worked in the settings and the Apple website everything you you could take the check to figure out why Facebook’s verification code was not showing up in my inbox .

So my question is how can I figure out why I can’t get a verification code to show up In my inbox to my iCloud account?

And yes I have checked my notification settings as well
