I'm using the basic Sync app (not Pro) to synchronize a folder between my Samsung Note Pro tablet and my Motorola DROID Turbo 2 phone. It worked like a charm earlier today (synching several GBs of data both ways between my devices), but after disconnecting and reconnecting my phone to WiFi, now neither device can seem to "see" the other; each device shows the other as "Offline."
Both are on the same WiFi network (don't think that's necessary, but they are), and both have Internet access. Restarting the Sync app on both devices hasn't made any difference. Is there any way to refresh that status?
