If priority of links is concerned, for Realtime or Failover mode, if you prefer WiFi over Cellular, you can check the WiFi First switch. In Realtime mode, this way, data will go over WiFi most if it is good enough. Otherwise, if Mobile over WiFi is preferred, then check Mobile First switch. Or let both switch unchecked, so in realtime mode, data will go over Mobile and WiFi at the same priority according to the realtime dynamics.
