Facebook jpg appears on Adobe file list?

Hi there

Hope you are doing well and thanks for reaching out.

Would you mind sharing more details about the issue you are experiencing? What is the workflow/steps you are taking? A small video recording of the same along with the issue as it occurs would be very helpful for more clarity.

Also share the version of the OS and the Acrobat app you are using, tap on the profile icon > About Acrobat and try to update the app to the latest version from the App Store / Play Store  and reboot the device once and check https://helpx.adobe.com/acrobat/mobile-app-faq.html

Let us know how it goes.
