Why does this happen?
The message can appear if:
you open a link to a job that is assigned to another driver,
the job has been moved to another driver,
you are logged in as the wrong user,
or the job is no longer active for you.
Most often it happens when you have been too slow to accept a job that an operator assigned to you.
How to get going again
Press My jobs in the message.
Open the job from the list in My jobs.
If the job is not there, contact the station.
What should the station check?
Ask the station to check:
that the job is assigned to the right driver,
that you are listed as the driver on the job,
that the job has not been cancelled,
and that you are using the right login.
If the job should have been yours
Do not carry on from old links or screenshots. Wait until the station has assigned the job to you, then open it from My jobs.
When is the problem solved?
The problem is solved when the job appears in My jobs, and you can open it without the message saying it is not assigned to you.
