I’m obviously being stupid… if I look at a remote device, it tells me Download Rate, Upload Rate, Address, Version, and Folders. Nothing about completion percentage. How do I see that information?
Everything has already been said above, but please also remember that when using the file watcher, there is a slight delay, i.e. by default 10 seconds for additions and modifications, and 60 seconds for deletions. If you modify and save a file, and then shut the system down immediately, Syncthing will not have enough time to pick up and sync the changes.
