Try disabling direct connection option, it may help.

Hi Matt -just want to confirm that the direct connection option is on the target computer, and that it is in the "Incoming Connection" in options - "Allow internet direct connections (BETA)" and that the box should NOT be ticked - please confirm

so i switched off the internet direct connections BETA on the target computer, as mentioned in my last message, but this makes no difference and it still hangs on the screen with the message"Connection established, waiting for incoming data..." This seems to happen only when i try to connect from a remote network, and when the target computer is locked (Windows)

Make sure you're on the latest version and send us the logs from both machines via diagnostic menu, please. Don't forget to mention this forum thread in the issue description.
