Had an inject node firing every 30min and after a few tinkering around and updating of the container it has stopped firing. Where can I check to debug?

Edit: seems that after waiting all day to execute it started working since midnight tonight...weird. Seems it takes several hours for the interval to kick in. Just now I see 2 sets of notifications one at midnight and the other at 12:30am so it is working now by firing every 30min at the top of the hour and half past the hour.

I guess my only question here is why does it take so long for the cron schedule of the inject node to kick in?
