We are running with version SUM 4.309-9.
When I would change the notification email and choose gateway ANY and replace email, it does not work. Below there is a message not all are online.
That is correct from the 58 there a few not online. But the changed is NOT procesed, when I choose all except the offline ones it works almost instant.
Also strange when log off the sum and in again all the notification settings are gone.
