Has issues syncing across multiple devices – Amazon WorkDocs Review

I am using workdocs on my desktop, laptop, and mobile phone with the sync app. The app is set to open and begin syncing on start up, however, it does not pick up items that I have just added automatically. It seems that both of the devices must be open, online, & on sync for my documents to be added to ALL DEVICES. What is going wrong here? This is a real pain in the butt.
