Some of my pdf files that I have completed reading and marked some points are suddenly vanished( highlighted points). How could I retrieve them? I trusted your APK so that for revision sake I won't go through all the way through PDF  and it sucks now . Would you please help me atleast for futures reference? @TEAM

What "vanished"? The files themselves? Your highlights? Where did you save the files, exactly? What application did you use? Please provide more details...

Sir,

I use Adobe Acrobat Reader APK to read PDF's and highlighted some important points for revision type stuff. I completed the session , after  few day's for revision purpose opened the same pdf (the one which I highlighted some points) the highlighted points are gone and a fresh pdf started to open . I don't know how they got vanished/deleted I didn't done anything wrong with the  application like clearing data, logging out, transferring files . Although they were deleted for revision I need to repeat the whole PDF (1000 page's) . How could I retrieve them? @TEAM
