I have linked several excel charts into a powerpoint slide. I used the copy from excel and paste into powerpoint as a link and keep source formatting. I set the links to update automatically.

When I change the graph data and/or scales in excel I don't see any updates in powerpoint.

I even tried an old add-in that was listed on some site, but it didn't allow the update to be seen either.

Not receiving any errors, just not seeing any change in the charts.

What am I missing?

Thanks!
