easy to use convenient. Except unable to load it on my Surface pro 3. Help with this would be great. I have to access through the intranet only. No app

Its been a good experience so far. Although I have only used the service approximately 5 times it has been an efficient way to produce some general documents.

The service is great and has come in handy in ways I had not expected. However, you lose 2 stars for my initial experience of first being asked to to pay, by a pop-up, to see a form that was submitted and then after paying being told by another pop-up that I need to upgrade to a more expensive plan. The first pop-up should have presented the correct plan. Felt a little like a bait and switch. But I gave you back one star due to the fact that support was able to fix the problem, quickly.
