Would you please provide more details about your problem so that we can diagnose the cause of the problem?
it didn’t working properly
Please describe what happened when you tried to open a PDF document.
Did you use the iOS "Open In" feature to open a PDF document in Acrobat Reader for iOS? Was the PDF document originally opened in a different iOS app (e.g. Apple Mail, Safari, iBooks)?
What did you see on the screen after you tried to open the PDF document? Did you see an error message? Did Acrobat Reader for iOS crash or disappear?
Thank you for your help.
