Since BT-RFCOMM is now broken on Across Center on macOS, I'm trying an alternative network connection, as per the (outdated) manual. I can select Network from the Configuration menu on the client side, but unlike as shown in the manual section 8.1, there is no equivalent setting on the server side. Presumably I have to set the port to the same value in both client and server, but this is not possible. Have the network capabilities been removed on the macOS Across server? I'm running 2.27 on Mojave. To what Across version must I downgrade to recover the network-based keyboard/mouse input channel?
