Welcome to Heroes, Alex!

Can you try deleting each slide that contains the Engage interaction that won't display the Next Slide button, publish your presentation to the web, and then close PowerPoint?  This will regenerate the PPTA file.  Then, reopen your presentation & then reinsert each of the Engage interactions.

If you continue to have issues, please submit a support case so that we can take a closer look at the issue:


Good luck, and thanks for your patience!
