Are you using the mobile app or desktop version to send the file?
Also ,you could try and share it to yourself and test if you get the same output .
What OS do you work on?
With the Reader DC mobile app you could not perform any sort of editing as it is a software meant to view PDF' only.
I'm using the mobile version on Android (4.4.2).
It's a fill-able PDF I created on PC (Window 7 pro).
On the PC it works fine, I just get this error on mobile, which is where this particular PDF will be used.
Thank you for your help.
Could you please update the Adobe Acrobat app and confirm if it is working fine for you? If it's still not working, can you share a screenshot to help us understand the issue better.
