The Information's sources said that Spiegel didn't consult with design or engineering executives about the new functionality or its intended goal. Additionally, when Snap tested the new design last December, the results weren't terribly positive, according to people who saw them. Some engagement metrics reportedly dropped and users watched fewer Stories. Some of Snapchat's designers conveyed concern over the design and the testing data, but the redesign was launched anyway.

Subsequent changes to the redesign were apparently made not by Spiegel, but by a team of Snapchat designers. Though Spiegel oversaw and approved the changes, the designers ultimately generated the plans for the redesign of the redesign. In an email to The Information, Spiegel said, "There is no doubt that collaboration yields better results :)"

We've reached out to Snap and we'll update this post if we receive more information.
