Experience Optimization issues resolved in SDL Tridion Sites 9.1

Several issues in the Experience Optimization feature were resolved.

It was not possible to use one query for multiple Experiments in multiple Regions
Problem: If you used two Regions, say, Example1 and Example2, and in the Content Manager Explorer Targeting screen, you created two Experiments, one in each, then when you viewed the webpage, only one Experiment would be displayed.
Solution: This issue no longer occurs.
In the Promotions tab, a Promotion that had been disabled and then enabled again still showed a Disabled icon
Problem: If you disabled a Promotion and then enabled it again, its icon would continue to show the Disabled status.
Solution: This issue no longer occurs.
