What's new
Clearer A2P registration rejections
- When an A2P 10DLC brand or campaign registration is rejected, Messaging now shows a clearer explanation of why, including campaign rejection reasons that were not shown before. You can see it in the account information on the Messaging Admin tab.
Known issue
- In Messaging Admin setup, the shortcut link to Business Hours in the setup pop-up doesn't open. Business hours and after-hours responses still work. To edit business hours, go to Setup > Business Hours directly. A fix is planned for a future release.
