When the slides from this presentation are cloned, the new presentation causes errors in PowerPoint when the user clicks on the File menu: “PowerPoint couldn’t read some content in AsposeClone.pptx and removed it. Please check your presentation to see if the rest of it looks ok”
After cloning depending on what version of office you have… for 2016 and 365, open the ppt file and you wont get any pop up’s at first. Then click on File on the top left corner and you’ll get the the ppt cannot read content error.
If you have office 2013 and below, you’ll get a ppt found a problem with content error immediately you open the file.
