I installed the plugin and everything works fine, the next day the icons gave place to the code ...

it will be possible for me to change the icons to PNGs or SVGs and avoid this error ..

I think I may have found a bug in the interactive video drag and drop. It appears that I must create all of the drop zones first. If I create a drop zone after I have created text, the drop zone will not have the text as a possible answer. It would make it easier if that was not the case. I had some drop zones that had a bunch of possible answers that I wanted to be able to copy and paste, but when I tried to paste new ones that already had the correct answers selected, it didn't recognize anything as possible answers. So then I had to start over.

I am having two videos and have a yes or no question attached to the video.

If the user answers "yes" it is a pass grade.

The second video should be available only if the user views and achieves a pass grade in the first video.

But even if the user answers "yes" the video activity is never marked complete.

I am attaching screenshots of all possible settings for video activity that must be marked complete if the user gets a pass grade.
