I'm running and A/B test with Google Optimize on one of my pages. This page is shown on multiple website on different domains through an iframe.
So, domain of my page is different from domain of the website hosting the iframe. I have no control on the website hosting the iframe.
The problem is that I'm not seeing any data collected from the Experiment in Google Optimize. I suspect that iframe an Google Optimize don't work smoothly together.
I can't find a clear answer on the documentation or in another questions online.
Do you know if is it possible to run an AB test inside on iframe hosted on a different domain? If Google Optimize is the problem, do you know other tools that work properly in this situation?
