I receive many PDF attachments through email and the majority of them can be downloaded and opened without a problem. However one company sends PDF email attachments which I can open on my PC. However with the iPad viewing the same email and attachment, while I can see the "paperclip" icon the attachment has not downloaded and so cannot be opened. I use Adobe Reader app & also have Goodreader app but they are no use as the attachment does not download. Could the company be using a PDF format/version which is compatible with Adobe Reader on the PC but not with Adobe Reader on the iPad. This is very frustrating and hopefully someone can assist or give me some guidance. Many thanks in advance.
