The AI Portraits Beta guide says on topic 11 that we can preview the effect by tapping on the preview screen, however this is not working.

I also tried pushing to the device and got an error "Something went wrong. Failed to Generate Your Appearance).

It only works when I publish the Lens.

Here's the guide link:
