Hi,
1. There is no issue with opening original file by PDFSharp. Is it possible to not corrupt file after form filling?
2. I have the similar issue with another file. Original file: www.dropbox.com/s/t5jjnci2kz4xua7/REAL.pdf

This one is much better.
I've found only warnings but no errors in the PDF syntax.
May you provide also a filled document?

Are you filling the forms in interactive mode (the user is touching on fields) or programmatically?
If programmatically, may you send a sample of the code you're using?

I'll move all the updated information to the developers.

We are using interactive mode.

So, with our out of the box code?

I think I've much more information now and my colleagues should be able to work on a fix.

So, with our out of the box code?

Yes. We just use cordova plugin. And we pass file to the server after it was filled by user.

Here is a link to the file after editing: www.dropbox.com/s/7xeesdbnwxablmc/Edited%20REAL.pdf
