WiFi automatic upload not working

While testing out automatic upload of data to the portal from a station, I've run into several problems. First, the station will not remain online indefinitely, and seems to time out after ten minutes or so, despite my having selected "Always on" from the Network: Schedule menu. Second, the station doesn't seem to send data to the portal despite being attached to an AP with internet access. Third, while connected to the station through the local WiFi network, the "Enable" button for Automatic Upload Settings doesn't seem to do anything, or toggle to "Disable" like it does when connected directly to the station AP. Also, when connected to the station through local WiFi, the WiFi Networks screen in the app doesn't show the AP that the station is connected to.
