I feel like I should be able to do this, but if I want to create an html block that displays on all Custom Certificate activity pages in all courses - How would I configure this? After testing all the options I haven't accomplished it:
On all Custom Certificate activity pages in each course
How many certificates do you have in your courses?
I think there is a block that goes on the Dashboard that shows all the certificates students earned, generally. I'm not sure if it is a plugin or not.
