Users are experiencing their Apex Class batch jobs being only processed at 15 minute intervals; it's being put on hold in the Apex Flex Queue and it doesn't matter what time they submit the jobs to run. The timing of the queueing / holding & processing of the Apex job is consistently running the jobs at the 15 minute increments on the hour; Example, 1:00PM, 1:15PM, 1:30PM, 1:45PM, and it repeats on the next hour for any jobs submitted and in the Apex Flex Queue. Any help here would be appreciated as I am not a developer but support keeps directing me to post the question here for developers to assist me. Thank you in advance!
