MMS delivery to AT&T destinations from 10DLC long codes returned to normal latency as of 18:30 UTC. Messages delayed during the incident were ultimately delivered; no resend is required.

We are investigating delayed MMS delivery to AT&T destinations. Messages are being delivered, but with delays. SMS to AT&T and MMS to other carriers are unaffected. We are working with our downstream partner to identify the cause of the delay.
