Cortana and Gmail

[WPCentral Question]

Loving 8.1 and Cortana with my google contacts and messaging, but can't get her to work w gmail. I read that I just need to authorize her to use my google accounts, but I thought I did that. Anyone able to walk me through this, so I can tell her to send an email w gmail to one of my contacts and she will do it (just like she calls and texts)? Thanks!
