**For customers with multilingual sites it's a must to allow a/b testing for pages with translations.**
The actual solution recommended by the HubSpot support is an evil hack around that undermines all developers efforts to provide easy to use multilingual solutions.
"The A /B test is attached to the "standard" language, in your case EN, not to both languages. If you want to run both languages as an A / B test, you need to create separate landing pages, one for EN and one for DE. I would suggest that I have an idea in the Idea forum to create what a feature will be available in the future. For such an idea to be implemented."
