Resolved
We have since resolved this issue, and users can continue editing their Zaps. We would also like to clarify that this incident was only affecting editing up a Zap. Any Zaps that were live were unaffected.
Identified
We have identified the issue and are working to roll out a fix shortly.
Investigating
Mapping fields in the editor is currently unavailable. This should only impact editing Zaps and not Zaps that are currently live. You may see a message "No matching data found" when mapping fields from trigger steps. We will update this status page with more details on how things will return to normal.
