Thanks for reporting this issue, we are aware of this issue, as a workaround you can try downloading the PDF using some any other 3rd party file explorer on your mobile, and then can open the PDF using Adobe Acrobat.

Same issue. Are you saying that I am better to ditch Adobe and the PDF files i use that let my apprentices sign forms while in remote locations and use MS Word documentation that i can simply upload to my main desk top on my return to my office?
I have my PDF's on a Kindle Fire HD which is ideal for getting a signature. This worked well until today after returning from a 250 mile round trip to find i can't upload to the cloud as I have "no internet connection" in my home, or work.
Not the best company policy to promote 3rd Party apps because Adobe is now unworkable. I see there is a mountain of issues reported against your product.
Everything is updated now and i can't even sign in to my account from the App as i apparently have no internet connection.
Poor show Adobe, looks like Uncle Bill will get my vote for a workable product. Just means i have to spend my time making Word Documents from my PDF ones..... from scratch!
