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.

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.
