I have this same issue. Every time, I have to reconnect Dropbox. I might as well only use Dropbox.
Our company has multiple field workers who experience the same issue, any help would be greatly appreciated
We apologize for the inconvenience caused. We are actively investigating the cause of the problem. However, we are unable to reproduce the problem easily.
Would you please help us by answering a couple of questions?
(1) Do you have the repeated sign-out problem with Adobe Document Cloud and Dropbox (both)?
(2) When the sign-out problem occurs, do you always see the "Welcome" screen at re-launch?
(3) Would you be willing to back up your Local documents using iTunes for Windows/Mac, uninstall the app, and re-install the app to see if the problem goes away?
If you have been using Adobe Document Cloud and/or Dropbox as cloud storage, you may not have many documents that are stored locally on your iPad/iPhone. However, if you uninstall Acrobat Reader, iOS will erase all your local data (e.g. locally stored documents, preferences). So please be sure to back up your Local documents before uninstalling the app.
Thank you for your help!
