Issue: Experience Optimization — You cannot have multiple Experiments on one Page
If you create multiple Experiments on your Page, only the first Experiment will appear.
If you use two Regions, say, Example1 and Example2, and in the Content Manager Explorer Targeting screen, you create two Experiments, one in each, then when you view the webpage, only one Experiment is displayed.
This is caused by a limitation in Experience Optimization in Tridion Sites: it is not possible to use one query for multiple Experiments in multiple Regions.
