Investigating

We are currently investigating an issue with messages being over stamped with unverified that is affecting a small subset of customers that have account hierarchies containing multiple sub-accounts. For these impacted accounts, registered and verified alphanumeric sender IDs may be incorrectly replaced with unverified sender IDs.

Our engineering teams are actively investigating the cause and working to restore normal sender ID behaviour as quickly as possible.
We will provide a further update as soon as more information becomes available.
