Users May Not Receive Notifications on Slack Thread Replies

We’re observing positive signals after rolling back the deployment in test environments. We will complete some final validations before rolling back the deployment in the production environment.
Thank you for your patience as we work through this one. We’ll report back once production rollback is completed or if there are substantial updates to share.

Some users have reported issues with thread replies not generating a notification banner. We’re investigating the issue, and have identified a recent deployment as a possible trigger.
We apologize for the inconvenience and will report back as more information becomes available.
