Good Monday morning.  Just wondering if anyone else is having a problem with dynamic groups today.  We have several groups that have stopped processing.  All of these groups are based on Last Hire Date.  All have retain mapping selected.  I have people in several of the groups mapped to a learning plan.  First people are currently in the group but not mapped to the learning plan, so that is not working.  Second I created some additional groups this morning and even though in preview it show people they are currently blank.  Again these are based on last hire date so
