Dynamic Groups Not Updating!?

Summary

Dynamic Groups Don't Appear to be updating on Pod CHM

Is anyone else experiencing issues with Dynamic Groups updating slowly or not updating at all on Pod CHM?

I had a group that should populate around 4 a.m. not populate until about 9 a.m., and then another I created around 11 a.m. that has not updated.

Thanks for your help,
David
