Hi My watch just stopped uploading runs to Tom Tom Sports Connect (mysports.tomtom.com). I don't get any error message. It connects ok -- I get the GPS updates for example. On the settings page, I pass the connection test. My watch software is 1.8.52 and the serial number is HC62831XXXXX (gotten from the computer rather than the watch). It's connected to a Mac running El Capitan OS X 10.11.6 - can't go much farther as it is an old Mac. Thanks for any help.
