Prompt to Resume on the Restart Not Working

I apologize for the misleading answer earlier. I was using the modern player, but after reading your post again, I’ve just realized that the issue occurs with the classic player. I can confirm the same issue happens when the classic player is used instead. The 'Prompt to Resume' will only appear if the Desktop view is checked on a mobile device, which I don’t consider a viable solution. However, by adding or modifying a single line of CSS in story.html, I can get the 'Prompt to Resume' window with the Continue and Restart buttons, as shown in the screenshot. I honestly can’t recall how this prompt should look in the classic player, but I was able to properly continue where I left off or restart as intended. I would recommend reaching out to Articulate support so they can at least log this as a potential bug or similar issue.
