Please respond, your vtext isn't working

I'm trying to set up a forwarding for certain Gmail emails as I've done for years using my service provider extension. It's a very simple process. However with my switch to Xfinity, Xfinity is making it difficult for no apparent reason. Currently I can send an email to my [Edited: "Personal Information"] and also receive the response to that text in my gmail, so that part is working.  However when I try to add the VTEXT email (that I know is working) as a forwarding option, I'm required to verify the email by entering a code that is received by the VTEXT email. This should mean I receive a message just like I received my own emails via text, with the verification code. I NEVER receive it. In fact I don't receive any kind of notification from anything through Xfinity even though it's sending information to a vtext extension. I should receive something. It's upsetting to know that something is being sent to me and I have no access to it.

How can I get this to work? Where are my verification codes going??

Something being sent to my phone number at the vtext extension should be visible to me. I never ever receive any kind of alert, notification, or verification number from Xfinity- why????! Please help.
