I have a similar issue that seems to have popped up after the latest app update. To answer some of the questions you asked the original poster, the size of the fillable pdf I am working on is 244kb and when completed is usually less than 300kb. Previously I was able to save the pdf to my iPad, email it, or save it to a cloud service (Dropbox, Google drive). Currently I am only able to save the pdf to the iPad and then email the file. However it is not saving all of the changes on the document. With a three page fallible pdf the app will save the information entered in check boxes, or drop down menus but it will not save free form typed information. I have tried saving the file to the cloud while connected to two different WiFi networks and cellular data network and it does not work on either of them. One of the ways to send the file does not attach the file to the email. If I rename the file I can send the file attachment from the “My Documents” view. However the pdf still does not have any information saved on the second or subsequential pages. I have tried other fillable PDFs and a single page filliable pdf seems to work okay, but multiple page fillable PDFs wont save and can’t be emailed.
