We created a sample course with the "Prompt to resume" option enabled. When we test the course on an iPad in the Safari Mobile browser the course will not resume. We get the prompt (Continue or Restart) buttons and when either of them are tapped a play button appears and it will not play; it just has a the loading icon. I have attached a screenshot of the player setting and the play button getting stuck.
Is there a setting we need to change or is this a known issue?
