Request a signature email has no link to follow to sign

So I've sent myself a document to be signed, but when I open the email, there is no link to follow to sign anything. If you see in the image below there is nothing to follow. I followed the steps on the adobe website on how to send a document to a user to request a signature. I sent it to myself as a test, created the test document in acrobat on a licensed account and ensured the document was attached and followed all the steps. This is what I received and there's nothing for me to click to sign.
