Some iOS users are experiencing errors when sending messages

Issue summary:
On August 21, 2023 from 3:33 PM PDT to around 5:41 PM PDT, customers using the iOS app may have experienced issues sending messages.

A code change inadvertently introduced an error in our message validation logic, preventing the iOS app from sending messages on a first attempt. Some customers may have been able to resend messages successfully.

We identified and reverted the culprit code change, resolving the issue for all affected customers.
