Customers might see issues with SMS and MMS messages failing to send on iOS 16 when the Cisco Secure Connector is installed. We have identified a temporary workaround for Verizon customers. Others carrier workarounds will be added when they become available.
We will also update this once a permanent fix is identified.
There are two workarounds available. The first is to add a domain to your internal domain list in the Umbrella dashboard. If that does not work then you can turn off wifi and the SMS messages should start working.
These workarounds do not work 100% of the time and should be tested prior to mass deployment if possible.
- Add mms.vtext.com to your Internal Domains list in the Umbrella dashboard.
