Thank you for highlighting the problem. May I know what is the version of iOS and Adobe Reader you are using?
I tried your workflow and yes it is not bringing up Google Drive or Dropbox app if we do it just after signing the PDF. Let me check more details about it and what seems is the document is not saved just after signing that why it is not able to bring up those app. If we go out and come back again the document gets saved with signature and Acrobat is able to call drive and dropbox.
We're using an iPad Mini 3, iOS 9.1, Adobe Acrobat 15.1.1 (127483).
Has this bug been fixed yet?
I just reproduced this in our latest build, so it has definitely not been fixed. I manage the development organization responsible for Acrobat iOS and I haven't seen this issue before. It's possible that it got lost in the communication between teams, but I cannot say for sure what happened.
I'm going to file a bug so that we can fix it. Thank you for contacting us and I'm sorry that we're just now seeing the problem.
We just released the new update (16.02.23) to the App Store on February 17, 2016.
The update includes the fix for the particular problem that you reported.
Please give it a try and let us know what you think.
I have a similar problem, if not the exact same problem...
When in Reader on the iPad, I click at the top where it says 'Local', and then select 'More Locations', and then click 'Google Drive'. I find my PDF, and open it. So far so good.
I sign the PDF, and click (top-right) and the status at the top says "Comment". I add my signature, and click 'Save' in the top-right, then I click 'Done' in the top-left. Lastly, I click 'Back' in the top-left...and I get this message:
"Document Saved", but nothing happens! My document in Google Drive is not updated with the signature, nor is the document saved anywhere else (e.g. Local, Document Cloud).
