Hello,
in the doc as well as in the FAQ i am pretty sure i wrote to always use V1 and that Google does not like redirects. As a general rule, V1 works in 99,99% of all cases and it works great with google. Dont use V2/redirect with google.
I have never experienced the affiliateID not showing, i would need more info what URLs you used on the interface. Maybe your browser ha javascript disabled?
