Incident

Issues sending messages when using certain elements of Block Kit

Issue Summary:

On April 3 at 1:23 PM PDT, we made a change to our Block Kit framework that prevented apps from using blocks containing several types of elements: specifically, the date picker and most of the select menu elements. The relevant change was identified and addressed at 2:11 PM PDT and we were able to restore these elements at 4:03 PM PDT.

We’ve been given the all-clear! All messages from Block Kit apps should be sending successfully once more. Thanks for sticking with us through that. We really appreciate it.

4:20 PM PST

We’re aware of an issue where messages from apps might not be posted if they contain certain Block Kit elements. Apologies for the disruption, we're working to resolve this.
