OK, thanks! I did read the documentation and it starting to make a little sense. I was able to get the single event popup to show up. However still a problem. In grid view, the popups work for the current month, but as soon as you navigate to another month, the popups remain completely empty. When I refresh the page, the popups show up correctly. In List view the popups populate correctly. I observed this both on Edge as well as Firefox. I disabled the cache for this page but it did not make a difference. Any suggestions?
Thanks again!
