Blank pdf on IOS 14.2
Application Type


We are developing an mobile app to preview PDF file.

It works well on IOS 13.4 and 14.4. but show blank content on IOS 14.2. 

I can be sure that the file exists in the device summary.

since it shows the thumbnail when I share it.

What is the possible reason for this?

and I try to write log after place "OpenDocument" action. It interrupted at OpenDocument.
