I have tried many times and several ways to change the footer of the master slides in my documents. I am trying to center the footer, move it down one line and change the character size. I am also trying do so similar things to the page number. When I make the changes and go back to normal view, I can see the change reflected in the charts. However, after I close the pptx file and open it again, the changes have been thrown away. How can I make the changes permanent?
I did this using View/Mater Slide. Then, I picked the slide I wanted to change, made the changes, then did a View/Normal View. Then, I viewed the changes I made reflected in the charts. The changes were there. I then clicked the red X and saved the changes. Then, I opened the pptx file and the changes were gone.
