hi all
just wanted to save some time for you in case anyone has the same problem I did :
I have been using mapmytracks for live tracking for a few years without any problems.
It was not working last time I used it though.
I got error in orux : "mapmytracks error: unauthorised" when recording a route and livetracking.
After lots of investigation I found that since Jan 1 2019 you must be a "plus" user on mapmytracks, a free account is not allowed to do live tracking.
It costs $30 per year. Details here: //https://www.mapmytracks.com/plus
I hope this helps someone.
