I was able to resolve the “View Quiz” issue by deactivating all plug-ins and switching to the twenty-twenty-one theme. Also the images are no longer bleeding over into other questions.
However, the formatting problem with any text between two dollar signs remains. This looks like a real bug in the application. It is a problem with both answers and questions.
Also I ran into a problem with trying to use the “image” answer type. When I add media from the library to an “image” answer it displays on the page as the non clickable URL: https://frickcpa.com/wp-content/uploads/2022/10/MyImageFile.png
Why doesn’t it just display the image?
