We are pleased to inform you that the issue with Messaging defaulting to internal notes has been resolved. We appreciate your patience in working with us to resolve this issue.
Root Cause Analysis
A recent code change revealed a timing problem when creating a new messaging ticket. Sometimes, the composer loads before the ticket data is fully ready, so it can't correctly identify the ticket’s original channel. This only happens with new messaging tickets when auto-accept chat is enabled.
Resolution
To fix this issue, our engineers reverted the change that caused the timing problem back to its last known working configuration.
Remediation Items
Make sure to test how the channel switcher responds when there is a delay in loading ticket information before deploying the changes to avoid these issues.
