How the sync feature work?

[awindowsuser11]

I have actually managed to sync (pair) my computer and my phone. Now the question is, how do they sync? I have a home wifi connection, and both my devices are always connected to it. Now, do they sync automatically when I open Flow tube on my PC, or do I have to manually sync them every time?

In the current Android and desktop implementations, this is a manually started transfer session, rather than an always-connected sync relationship. Being on the same Wi-Fi makes the devices reachable; opening the PC app doesn't itself start another transfer.

For another sync, open the sync screen on both devices, choose the sending/receiving direction and data, connect using the QR/code, and complete the confirmation steps. Once a transfer finishes, later changes aren't continuously pushed to the other device; start another session when you want to transfer them.

The Android SyncManager runs a session from host() / join(), marks it Done, then closes the connection and server in cleanup(). The desktop sync store likewise has explicit startHost, hostReceive, and join actions.

This is based on the current source on both sides; I haven't tested your particular installed versions on devices.
