Frequently Asked Questions

Why do my PDF signature fields disappear on my iPad?

This is often caused by compatibility issues or bugs within the specific version of the mobile PDF reader. When the app processes the document for sending, it may fail to render interactive signature layers correctly.

Can I recover signature fields once they are removed during sending?

Typically, once the fields are stripped from the sent file, they cannot be recovered in that specific outgoing copy. You will need to reopen the original source file where the fields are still intact and try sending it again.

Are other form fields affected by this iPad bug?

According to user reports, while signature fields disappear, standard text fields, checkboxes, and drop-down menus usually remain intact during the sending process.
