For our business, we use Dropbox and Acrobat Reader. We open and fill out documents stored in Dropbox in Acrobat Reader. We then export the file back using the "copy to Dropbox" function. Up until recently this function worked. I am thinking there was an update to the app removing this feature. We use the app on our iPads or iPhones. I have spoken to Dropbox and they said everything is linked on their end. Apple said it has nothing to do with them. I tried calling Acrobat support and could not get to anyone who could help through the automated system. I started a chat with a rep who informed me they only know how to troubleshoot desktop apps then he ended the chat. How do I get this feature back?
I hope you are doing well and sorry for the trouble you had.
There have not been any changes in the recent update that would impact the workflow or the behavior of copying the PDF files back to Dropbox.
Would you mind sharing the current version of the Acrobat Reader app installed? Click on the profile icon available in the Reader app, then select About Adobe Acrobat and share the version details. Also, a couple of screenshots of steps/workflow would help.
