Hello! Thanks for a great app! I would like to be able to synchronize two folders on one computer. It is necessary to back up to a local network-attached storage mapped as a network drive. I added a folder and tried to specify The secret, already existing on this computer, but the program is not allow it. Then I tried to use read only secret and predefined host via the loopback interface. It did not work. In the tab "Devices" line is not displayed and synchronization does not start. I think that there should be no difference, I connects to another computer or to yourself via loopback interface? Thank You!
