Hi there. Syncthing on Windows 10 does not see other devices. But other devices, like Android phone and iPad can see the computer and add each other, share files, but not to and from the computer.
It doesn’t work if I have all addresses set to “default” and “dynamic”, nor if I set address of my wi-fi or devices IPs.
EDIT: I have local discovery turned on.
About the setup:
Computer – Syncthing v1.29.2, Windows 10 (64-bit Intel/AMD);
Phone – Android 13, Syncthing-Fork v1.28.1.1, android (64-bit ARM);
iPad Pro – iPadOS 17.5.1, Mobius Sync v1.27.10-g17002a0a8-i, iOS (64-bit ARM).
