Frequently Asked Questions

Why does Adobe Mobile Reader say 'error occurred' when I try to share a signed file?

This generic sharing error is commonly caused by unflattened interactive signature fields causing processing glitches, an outdated application version, or temporary network connectivity issues blocking the mobile share sheet.

How do I find my device's make and model for app support?

You can find your device's make and model by navigating to your smartphone's system Settings and looking for the 'About Phone' or 'About Device' section.

Will flattening a PDF remove my digital signature?

Flattening a PDF visually merges your electronic signature into the background of the document itself so it cannot be altered. While basic electronic signatures remain perfectly visible and intact, flattening the file will invalidate highly secure, cryptographic digital ID certificates.
