Problem signing in to YouTube with DEVONagent

I am unable to sign in to YouTube using DEVONagent. When I try I get a page with the alert “There was an issue signing you into YouTube. Troubleshoot here”. Clicking on the “here” in this message brings up a choice box which is not helpful at all. I have always had this problem with DEVONagent but can sign in with Safari fine. Has anyone else experienced this problem?

What OS are you running?

Yosemite 10.10.4

I’ve got an issue filed with Development on this.

Cheers!
