A2P 10DLC Campaign Vetting Delays: We are experiencing delays while vetting 10DLC campaigns. Our third party is reviewing campaigns manually, and due to the high volume of requests, a queue has built up. Campaign reviews are expected to take longer. Twilio is working with the provider to help expedite this process. New details will be shared in our incident report as soon they become available.
