It’s Behind You
The traveller pin for your destination will always be shown on your destination name on the map. Sydney on Sydney, Rome on Rome, Siem Reap on Siem Reap – you get the gist.
If you only see an icon pin on the destination name then give that a click. It may well be that the travellers pin is hidden behind because someone has created a chat with Sydney as the destination. This is as opposed to say a specific location like the Sydney Opera House. The latter of which would be plotted on the Sydney Opera House.
