You can then select the Edit Pen for what you'd like to edit > Edit details > Save, and click off the drawer to return to the Jobs list.

To edit a Job in the App you will need to go to Jobs > search the job you would like to edit > swipe left > select Edit and make your changes > save / dispatch.
Through the Diary on the App a job can be edited. Diary > press on job that you would like to edit > select edit > make changes > Save.
