Oct 13, 16:10:00 GMT+0
Resolved - Earlier today, some customers experienced intermittent failures when sending and receiving messages through the TOC webhook platform. The issue was triggered by a media transcoding error when processing certain MMS attachments, which caused message delivery and authentication to fail intermittently for affected accounts. A fix has been identified, tested, and deployed. Media handling has also been improved to support a wider range of attachment formats going forward. Message delivery is fully restored — no action is required on your part. If you continue to see any issues, please contact support..
