I downloaded the documents on my Macbook using my Adobe ID but cannot see ANY of the documents when I have "Authorized" my Adobe Id in the Samsung Galaxy Tab A 10.5 which I bought recently just to study when travelling. I have re-installed the app on the tablet many times without any luck. While downloading from the Play Store, there is a message which says that this App is not 'optimized" for this device. Can't Adobe fix this issue ASAP? Or we have to suck it up because it is free while they collect the licensing from the document publishers. !
