The synchronization should be simplified. Other solutions like Dropbox and OneDrive have apps. I tried using the mobile version, but it didn't work properly, that needs to be improved. It was cumbersome. It's a good solution for a small organization like ours, but it really depends on your use-cases and the size of your organization. 

I had a very bitter experience with their mobile app. It was challenging to even download it and once I did, I wasn't even able to log into my system. The mobile app needs to improved for easy use.
