The job scheduler appears to have halted and it will not process any jobs in the queue. The jobs are in Waiting/Scheduled/Processing/Cancelled status but not changing statuses.
Other jobs of different types may or may not be running.
This is caused by a disruption in the job scheduler, which runs on the background (BG) service. If the jobs were not paused and/or were not allowed to complete prior to the disruption, the job scheduler will not recover.
If the above does not help, proceed through the following steps.
Check for issues via Home > Reports and Jobs > Jobs > Scheduled Jobs
Important: Run these steps in sequential order
