I don't think v3 is integrated with XC5 or 4 for that matter at all. Maybe XC will do that when Google releases v4
On a side note the new GA4 has been out for a while yet the GA module only works with Universal...
I don't really have any desire anymore to integrate any Google related services, or FB, or Twitter, or any of the other blood sucking so called "high tech", "social whatever", etc. I am happy to stay away from them and for personal as well.
