The App is wonderful and I gave you 5 stars,but there are 2 bugs.
1) the switch for html enabled doesn't works
2) Only in the Ipad version - isn't impossible to attach file from the App PDFEXPERT, this option works well in the iPhone version but doesn't works in the Ipad version. Furthermore only in the ipad version, sometimes I receive email with attach file and is impossible to see the file, I see it in the iPhone and not in the ipad, is like if the file is out of the email and you can open the file because you don't see the file.
This bugs happen not always but sometime.
