I ran into this issue today where every cron job would get created a few seconds after when it was supposed to execute. Because of this it would fail to run.
Notice the “send_notification” cron job at the top was executed, but then never finished and the “Too late for the schedule” message started shortly after. Geil Berkers also encountered this issue with Magento 2 in his post https://gielberkers.com/solving-too-late-for-the-schedule-with-magento-crons/ .
The issue with that cron job caused all subsequent crons to become too late for the schedule. As a temporary solution I manually entered a date in the “finished_at” column of the “send_notification” record and within a few minutes all crons started running again.
