Notification when opening pdf: your last acrobat session ended abruptly

I'm having the same issue, this pop-up occurs every time I open and close a pdf. Clicking restore does nothing

Hi Rob,

The dialog box shown above comes up, when a document was closed abruptly. In past, users used to complaint about the lose of data either due to system shutdown or Adobe Reader closed automatically or crashed because of some technical glitch.

This feature "Reopen PDFs from last session"  have been introduced in the latest release May-2019. Its a design behavior now, and it can't be disabled.

What's new in Adobe Acrobat DC

Clicking restore doesn't even do anything so I'm not sure if it even works.

This should definitely work, and to test you can make a slight change in the file and close without saving. Check if you get it back after restoring.

Hope this answers your query.

Thanks,

Akanchha
