The file was generated by using LaTeX and the embedded figures were made by Apple Keynote and Quartz PDF.

In old iOS versions about one year ago, this issue did not exists. Acrobat Pro or Reader for Mac (2021.007.20099) does not have this issue either.

Hello Ria,

Thank you for the reply.

A1. I myself use Acrobat 21.10.00 on iPad OS 15.0.2 + iPad Pro (10.5-inch). But most of the students (about 50 people) in my class, who opened my PDF exam on their iOS or Android devices, complained that the embedded figures are not shown properly. So the problem can be reproduced in various different combinations of devices, OS, and Acrobat versions. You can see the figures if you pinch out to zoom in.

A2. At least a few files.

A3. Right. Please also see A1.
