App removes digital signatures from PDFs when reading these!

App removes digital signatures from PDFs. Totally defeated the purpose of using PDFs for contracts. Uninstalled.

Crashes when Deleting Pages of a PDF

Itโ€™s a pretty useless app if you use it to remove pages from a PDF file because it just crashes after a few pages are deleted. It returns you to the file unmodified.

Crashing App

This app keeps crashing as I airdrop documents from my laptop over to this device. Not impressed.
