Where is the support?

After going through the painful process of installing this and getting it to work, there is no ability to zoom in to be able to read the tiny text in the attached pdf doc. Tried to request support and prompted for s username which I dont have. Clicking into the app tells me nothing about s username. I agree with others that the company who decided to use this to encrypt their emails didnt think it through.
