I have the Samsung S 10. I had a simple version of Acrobat Reader and was prompted to update the ap to this DC version. Since then, I can not go directly to my files, I can not move documents from my flash drive to my files.
Unfortunately, you will not be able to move files to different folders with the latest version of Acrobat DC. However, you can directly access your documents in the 'Local' tab. This lists all the PDF files available on your device. Sorry for the inconvenience.
