Having Trouble Advancing PowerPoint Slides?
Possible Reasons for PowerPoint Slide not Advancing
If a PowerPoint (PPT) slide will not advance automatically, nor with the mouse click, there could be several reasons for this issue.
One possible reason is that there may be some animation or transition settings that are preventing the slide from advancing. Check the slide's settings and make sure there are no conflicting animation or transition effects.
Another possibility is that there may be a glitch or error in the software. In this case, try closing and reopening the presentation or restarting the computer to see if that resolves the issue.
