If you're using the latest version of Acrobat DC on iOS, you'll open to the Local tab. In that section, click the ... icon at the upper right, choose Select from the menu. Select the file to delete, and press the Trash Can icon.
I don't believe you can remove files from the Recent list.
Thank you for your response. The item I'm trying to delete is not showing
in the local tab. It is only in the recent tab, with a cloud icon on the
right hand side. There is no option to delete. Very frustrating.
If you see the cloud icon, it means that the document is stored in the Adobe Document Cloud.
Would you take a look at this FAQ document?
Once you switch the file location to Document Cloud, you can delete the document.
Please let us know if you have additional questions.
Thank you, that worked.
