   As of 4:00 AM PT on June 5, 2025, we began observing issues with outbound SMS delivery affecting a subset of customers. This disruption is also impacting the delivery of verification codes required for account creation and login, and may be preventing the successful sending of secure messaging invites. Our engineering team is actively investigating the root cause. We will share updates here as we learn more.

   Our telephony infrastructure partner has identified this to be a platform wide issue on their end. That being said, we are seeing a reduced rate of SMS delivery failures in the last hour.
