What do you mean by "sending email from the browser"?
Have you confirmed that all of the script steps are FMGo compatible?
Where are you saving the PDF before you attach it?
Are you able to successful create and view the PDF without trying to email it?
What I mean by sending it from browser is sending the PDFs from FileMaker Go Device tab.
The script runs, creates the file, pulls the email window up and freezes. When I close and reopen FileMaker Go the PDF file is created under the device tab. It can be opened but when I try to send it via email it pulls up the email window and freezes just like the script. Hard restart will fix this. In the mean time I deleted the script and re-wrote it. So far so good. I am just puzzled why is it only dowing on the iPad Air 2.
