Why does the BIM360/C4R Publish Task not run when scheduled when there are changes?

Hello,

We have several BIM360/C4R scheduled tasks that are not running even when we can see an Update is Available. It is hit and miss as to when these seem to run. We get no errors or completed info either. Not sure what we need to do on our end to facility this task. The publish needs to happen daily and it is not. Team is losing confidence in the product.

Thanks,
