Why does this happen?
The job needs to know which vehicle you are driving. If you start or update a job without a vehicle selected, Assist may show this message:
You have not selected a vehicle, please go back to “My jobs” and select a vehicle.
How to fix it
Go back to My jobs.
Tap Vehicle at the top of the page.
Select the vehicle you are using.
Open the job again.
Continue with the status or navigation.
If the vehicle is already in use
If the vehicle is in use by another driver, you will be told before you take it over.
Only take the vehicle over if you are actually using it. If you are unsure, contact the station before you continue.
If the vehicle is not in the list
Contact the station and ask them to check that:
the vehicle is registered,
the vehicle is active,
and that you have access to select it.
When is the problem solved?
The problem is solved when the correct vehicle appears in Vehicle and you can open the job without a warning about a missing vehicle.
