Azure CNAME / A record confusion

Question

I've set up my first site on Azure. Let's call it 'mysite.org.uk'. I've uploaded the files to Azure as a shared Azure website. It's accessible at 'mysite.azurewebsites.net'. Now I want to test it out by pointing a live subdomain to it, so basically I want it to resolve with the URL 'cloud.mysite.org.uk'. I've read the documentation and it says that before I can add an A record to my domain to do this, I need to create a CNAME record. The instructions it gives are:

The DNS record for 'cloud.mysite.org.uk' that points to 'mysite.azurewebsites.net' could not be located. If you want to configure an A record, you must first create a CNAME record with your DNS provider for 'awverify.cloud.mysite.org.uk' that points to 'awverify.mysite.azurewebsites.net'. First allow the resource record to propagate, and then create the A record.

Okay, so I've logged into the Plesk control panel of the current host (where the DNS is controlled) and added a CNAME record with 'host': awverify.www.mysite.org.uk. and 'value': awverify.mysite.azurewebsites.net. I did this more than 24 hours ago so it should have propagated by now, but when I try to add the domain in the Azure portal it still tells me there's no verification CNAME record. Similarly when I ping awverify.www.mysite.org.uk it doesn't resolve (surely it should if it's set up right, as it's a new record, so it shouldn't rely on DNS propagation time?).

To be on the safe side I've also created a CNAME with host: awverify.cloud.mysite.org.uk and value: awverify.mysite.azurewebsites.net and that too isn't working. In fact when I add these CNAME records Plesk tells me:

Unable to resolve the canonical name awverify.mysite.azurewebsites.net.

Anyhow, I'm a little bit stuck. I thought I'd followed the documentation pretty closely but obviously something isn't right.

If anyone has any pointers I'd be most grateful.

Thanks

It must have been a propagation issue oddly, as 48 hours later it works when I add the domain to Azure.
