Cron appears to be working, as some courses are sending the posts (we have users set so they have them sent as digests once a day), but others do not send them.
I have a test account created, and have it set to receive posts immediately. This account gets all the posts from the course that is not sending them to accounts that get digests.
We are running 2.6.2+ (Build 20140422)
Anyone have an idea why some courses work correctly and some do not?
