How can you improve this? You can fire the person who decided it was a good idea to make it seemingly impossible to delete a gotdamn file? How do I delete?! Why isn't this simple and intuitive?! Please call someone from Apple to help.

Apologies for the inconvenience. In Acrobat web, please click the "..." icon in file list either on the home page or the documents page. A button to delete the file would appear in the menu that pops up. You should be able to delete the file from there
Please let me know if you have further questions.
