I love everything about this software, it's very intuitive for my clients who are not tech savy at all! They can easily navigate around their space in order to find what they're looking for without any problems or issues whatsoever because of its simplicity. Nothing really. It is pretty much perfect as long as your client/employee has basic knowledge on how things work online (like social media). If that person doesn't know anything then there could be some challenges but nothing major either from an admin point-of-view so far. We have had no complaints yet regarding our employees working remotely which was one of main concerns since we were thinking if people would actually use it when out office hours are over due to Covid 19 restrictions.
