No ticket notifications sent (SendAgentNotification) after upgrade

[ftmgatset]

After upgrading from 6.0.3x to 6.0.40 with otrs-community-edition-6.0.40.sh script no Ticket Notifications are sent anymore to agents after valid ticket actions (Ticket creation, ticket updates etc.)

1. Verified that no SendAgentNotification event is created in Ticket's history
2. In Ticket notifications, ticket notifications are in valid mode, rcpt to --> Send to All agents subscribed to the ticket's queue, event --> NotificationNewTicket / TicketCreate, Email as method enabled
3. Users are in correct queues as the tickets, Users have enabled the notifications in Personal Preferences
4. NotificationSenderEmail is already set

We are facing the same issue described above, with a migration from OTRS, non cumunity edition, 6.x to 6.0.40.
