Haven't been able to add a blank page to the 3 page form I was working. The instructional video indicated I should see a "Pages" icon on the Edit line. I didn't.

for the most part, all of the documents that i need have been found on PDF filler. I did have to find the 2016 1099 int form on another site, but at least i found it. This service has saved me a bunch of time by not having to type these forms on a typewriter.

Seems user friendly for the most part. It would be nice if the documents could be automatically opened in Drive without all of the signing in process each time

This is awesome - to be able to do things to a pdf that I have always wanted to be able to do, and had to do, but taking the long route - this is a HUGE time saver. I just wish that it was a one time price.

sometimes the app freezes and takes a few minutes to load which can be inconvenient when files are needed quickly. Also some features also drag for example the signature portion. Overall great app which I use daily for my work.

Digital certificates are electronic credentials that bind the identity of the certificate owner to a pair of electronic encryption keys, (one public and one private), that can be used to encrypt and sign information digitally.
A certificate stores the public key component of a digital ID. For more information about digital IDs, see Digital IDs. When you secure a PDF using a certificate, you specify the recipients and define the file access level for each recipient or group.
On the Protect tab, in the Certify Document group, click Certify. On the Certify Profile Wizard, choose the actions you want to permit from the Permitted actions list. Click Next. Select a digital ID to certify with, and choose whether to make the certificate visible. Click Next.
An electronic signature, on the other hand, is merely an image of your signature overlaid on top of a PDF document. You can do it with all kinds of apps, and it's what most people will require when they send you a document to sign. Send them a PDF file with a digital signature, and they won't know what to make of it.
