This is similar to what is happening to me. The difference is that it's my Android device that is not adding the folders. I just went through and removed all my legacy 1.4 stuff and set my NAS back up with 2.0. Seems to be working fine otherwise. Anyway, I am now on my phone. I wiped Syncs app data and went in and deleted the hidden sync folders. The Synced folders are still there. Now that my NAS is set back up, I have linked all of my devices. So my Android phone sees the proper list of my folders. I have simple mode deactivated. When I click on one of the disconnected folders in the Sync App, it prompts me to choose the folder name and location. This has changed slightly in 2.0, so instead of picking the exact folder as a location, you pick the parent folder and then specify the folder name that will be synced. I don't understand why this change was done, but whatever. So anyway, when I choose the correct location and name of my existing folder that has all of the files already, and press "Add Folder", nothing happens. It returns me to the list of folders, and the one i just attempted to set up stays disconnected. I don't see any way to enable debug logs on my Android phone. And I really don't want to delete all of the files off of my phone and resync them, because then they lose all of their "Date Modified" tags, leading to the order of the images to change on the phone(which is another gripe of mine, but I doubt that can really be fixed).
