The flow of inbound messages is now coming in, and we've identified the cause. We're working with our mobile partners to resolve the issue permanently. Any messages sent while the issue was occurring were queued, and therefore will be received.
We have been alerted to the fact that the platform is not processing or receiving inbound messages.. It is affecting the receiving of messages into our inboxes (both long numbers and short codes) from all mobiles. This matter is being investigated and we will update this notification shortly.
