Each mission's location is defined by a written address and a pin on the map. It's your responsibility to check this information before reserving the mission.
As a rule, if the given address differs from the placement on the map (pin), you should go with the written address.
If you're at the written address and this is different from the pin location a 'gps-error' will show up telling you you're not in the right place (pin location). You can choose 'Location is misplaced' and proceed with the mission. Below you'll find a screenshot of what it looks like.
Note that we'll check if indeed our pin location was incorrect, so only use this option if indeed our pin was misplaced. Otherwise this may result in your mission being rejected.
