Hello. Customers of our site are not getting email alerts when said customers are added to the 'request participants' field. If a help desk agent is added to the field, they get the alerts as expected. There is no issue security schema. Any direction on how to get the customers that we add to the 'request participant' file to get alerts would be appreciated, as it seems from the documentation that this should work out of the box. I manually added 'User Custom Field Value (Request participants)' on the notification scheme, but this does not appear to work either.
