According to Glasswire, Chrome and other Chromium browsers are constantly connected to the local IP address that happens to be assigned to the Nintendo Switch. I’m not sure exactly why Chrome is so interested in talking to the Nintendo switch, considering that it does not have any browser-accessible user interfaces, or indeed any network connectivity with other devices at all (except possibly with other Nintendo Switches, though I only have one).
Is glasswire mistaken, or is there something weird going on between Chrome and the Nintendo Switch?
