@lloback I followed the step outlined to test. After creating the qualifying test, l couldn't initialise the test. Can you have a look at the code pls.

@joy-ade if there is an error that is not related to this PR you should raise a ticket for it, and we can take a look into it. There was no change on this code to the actual creation or initializing a Mopup. The code here is only related to the visibility / disability of the button.
