how to add a contact to a group in Xfinity contacts?

I have  a name in my contacts that I now want to add to a group I already have set up.  How do I do that?

By following one of the most bone-headed procedures I've ever seen. See https://connect.xfinity.com/appsuite/apps/faq/index.html#addContact.

This works on a desktop or laptop, but I was not able to figure out how to do this on a phone or tablet. 

Howdy user_mzithi, and thanks for stopping by our community with your question 🙌 If you're trying to add a contact specifically to your email contact list, the link in the previous comment will provide a nice step-by-step on how to get that done.

Should you be referring to anything outside of your email contact list, please let us know!
