When trying to do a presentation using PowerPoint, slides are not being displayed or skipped.
There is a symbol on the slide that has a circle with a slash through it on the slide that is not being displayed.
- Click on the slide and go to the "view" tab on the top.
- There is an option that is "Hide", click on that and the Circle with the slash through it will disappear.
After both those steps have been completed you should be able to present the slide now.
