We have a whole bunch of activities set up, mostly lessons, but also databases and quizzes, that are set to release once a student has completed the previous task. We're getting a lot of students complaining they don't have access to the next set of content, even though they've completed the required tasks.
By the time i can get in and login as one of the students and check out what might be happening, everything looks hunky dory. they have completed the work and have access to the next task, just as it should happen. I've also had more than one student complain and then almost immediately say that it has been fixed well before any staff have had a chance to fix it. i'm beginning to think there's a time delay on the release of material restricted by completion. Does anyone know what's going on here? Could there be a time delay? if so, how long is the time delay, and why?
ps. we're using Moodle 2.3, and we're putting access restriction settings on lessons based on completion (at least 0%) of other lessons, and databases (based on receiving a rating for an entry)
