"Details can't be retrieved"
This message in an Android-specific error that may appear if you click the Details button for a job that is no longer available. The scenario indicates that one of two things may have occurred between the time that Jobulator notified you and the time you clicked the "Details" button.
Scenario 1: Another sub already accepted the job.
Scenario 2: The teacher or administrator is currently editing the job.
If the job is currently undergoing edits by the teacher, we recommend you click the Refresh button to check the job's current availability. Provided it was not deleted, the job should reappear once the teacher completes his/her edits.
