Not getting notifications for subscribed tickets

When I subscribe to a ticket, I used to only receive the external responses (nothing from our techs). Now, I receive nothing. I’m clearly subscribed but am not getting either messages from external party or our techs.

Hi @ajones

Please review the sets of alerts in Admin>Notification Center to make sure you’re alerted for Ticket updates. If there’s still an issue thereafter, please feel free to reach out to support for further assistance:
