Unfortunately we are experiencing issues with the live tracking funcationality of the service 21/21A (Spark) buses on our mobile app. 

This is due to a glitch in the tracking technology on these buses. All other services are unaffected. 

We are working to find a solution and anticipate things will be back up and running next week. Thanks for your patience. If you have any questions in the meantime regarding travel on this service, please don't hesitate to give our Customer Experience team a call on 01752 662271.
