Since the upgrade to 2.0, some of my shares stopped syncing. I use several Linux servers and several desktop clients with 2.0. The main thing that is different from a normal setup is that I created the shares with a key that is 3x as large as the normal key. Simply 3 keys put together as one. This did work perfectly with 1.4, but with 2.0 my shares stopped working and only the ones with a normal key work. Also, in the desktop version the shares are now seen as ReadOnly, while the key is a normal read write one. Are longer keys not supported anymore?
