Currently, we are in the process of setting up a server-side AB testing using Google Optimize.
We have done the implementation as per the following: https://developers.google.com/optimize/devguides/experiments
I noticed that when the following command is executed that the _gaexp cookie is not getting set correctly i.e the experiment ID is not appearing in the _gaexp cookie.
ga('set', 'exp', '$experimentId.$variationId');
I wanted to know if this was normal behavior for GO based server-side AB testing.
Any help would be much appreciated.
