Ive gived up using the Arriva live map App.

Since their last updated the App, the bus icon only moves when the App updates every 1 or 2 minutes ish, which is not real time. sometimes the icon says the bus has just arrived at peterlee bus station and next thing I know the bus has just gone past my house, Arriva needs to sort it out, before their updated the App you could see the bus icon moving along the road.
