Frequently Asked Questions

Why does Acrobat Reader keep signing me out of Document Cloud on my iPad?

This is caused by a bug in older versions of the app where it fails to properly retain your session tokens. Updating the app to version 17.12.15 or newer from the App Store resolves this.

Will I lose my saved PDF files if I update the app?

No, updating the app through the App Store will safely preserve your downloaded files and settings. However, any documents stored locally should ideally be backed up to a cloud service.

How can I check which version of Acrobat Reader is installed on my iOS device?

Open the Acrobat Reader app, tap your profile icon or the menu button, and navigate to 'Settings' or 'About'. The current version number will be displayed at the bottom of the page.

What should I do if updating doesn't fix the Dropbox connection problem?

If the problem persists after updating, try uninstalling the app, restarting your iPhone or iPad, and then reinstalling Acrobat Reader directly from the App Store. Re-authenticate your Dropbox account upon launching the newly installed app.
