Hi there 

Hope you are doing well and sorry for the trouble you are experiencing while reading the PDF files. 

What happens when you try to open PDF files via the Acrobat Reader mobile app? Do you get an error message? If yes, please share a screenshot for more clarity.

Is this an issue with a particular PDF file or with all the PDFs? Please try with a different PDF file and see if that works.

What is the version of the Acrobat Mobile app and the OS you are using? Tap on the profile icon > About Acrobat and try updating the app to the latest version available on the App/Play Store and reboot the device once.
