There are a few reasons why you might not be getting any jobs in the Available state, you should follow this list to work out the issue: There could be no jobs in the queue. If the fleet has enabled this try clicking "Bookings Queue" and you should see all jobs currently awaying a driver, if you can not, call dispatch to find out the queue length.
Your driver settings are incorrectly set, click on "My Settings" and ensure your vehicle size and type is correct, for example, if you've been left with the default of 1 passenger and 0 cases, then any jobs requiring more will not be sent to you.
You might not be scheduled to work at this time, call dispatch and ask them to check your schedule settings on your account.
Your pickup radius set on your account may not be reaching jobs currently in the queue. Please ask an administrator to check your "Pickup Radius" setting on your profile.
Automatic Dispatch maybe disabled by the fleet administrator, meaning jobs must be manually allocated by a dispatcher. You should speak to an administrator to confirm.
If you continue to face issues and the above list of potential issues does not help you resolve the problem, please contact support.
