Acrobat Reader ISO (for iPad) don't do forms
https://itunes.apple.com/us/app/pdf-expert-fill-forms-annotate/id393316844?mt=8 this is the only program for now that does PDF Forms on the iPad.
I find the same issue using both Acrobat Pro X and Acrobat Pro XI.
What I found to be contributing factors are:
1. programs running in the back ground
See what is running in the background and stop what is not required.
2. the overall size of the form (MB)
under “File”, “Save As” there is an option to Reduce Size of PDF.
I found this to help on some mobile devices.
how to you get your pro to work on Mac's. everytime i send a fillable pdf with a submit button Mac users can not submit (even after telling them not to use their Preview. They must use Adobe Reader.
