I found it surprisingly easy from both the admin side and the customer side. The admin side has a limited set of features, but they are very well explained. They are very simple to understand. It is very easy to find out what every feature does. It is not really complicated.
Sana provides an online university where you can learn everything that you need about it. When we needed to check a new feature or validate how something works, we found solid online information on their website. If there was anything that we couldn't find, or if we really couldn't understand how exactly something was working, their support was always very quick. So, it is quite easy.
