In the downloaded issue 73, there is a phantom page between pages 74 & 75.
When going from page 74 to 75, the phantom page usually appears for a brief moment, then the full page (Hello World) black on yellow ad appears.
The phantom page has a full screen image of a classroom, with an instructor looking over the shoulder of a girl using a laptop at the bottom.
The phantom page only appears when going from page 74 to 75, and not in the other direction. It doesn't always appear.
I can see the phantom page when using the FoxitPDF reader, but not Adobe Acrobat.
I was able to capture the phantom page by using a screen recorder and video editing software.
