Resume pop-up box is invisible in LMS
I'm experiencing an issue where the pop-up box 'Do you want to resume?' is invisible when Storyline courses are revisited in an LMS.
The box is there - I can see the cursor turn into a 'hand' icon and can select the two options (Resume and Restart) - but it's invisible.
This happens on Cornerstone (my client's LMS), and on Scorm Cloud.
This makes me think it's an issue with Storyline. Is anyone able to help?
