Classes not showing as viewed

After I have taken a class it is not showing up as viewed. Is there something I need to do after I have completed the class?
It can be confusing sometimes with so many classes.

Dear Angharad ~ we have a bug that results in people (like you) that are watching the class using an iPad not having the view recorded. We are working on a fix and hope to have the issue resolved soon.

Thanks for that.
