It would be so good if doing the rescheduling of class lessons at our end also coincided with email lesson notifications being altered accurately too. We always seem to have glitches getting the correct lesson link sent after we have rescheduled for public and school holidays. Any way this can be improved? 

Does this mean you need to reschedule all the separate classes to ensure they are synced/ ie all have the correct current lesson date highlighted? Or does changing one Sunday school class change all the classes we have loaded?
