since the last update photos within skills are finally also shown in android display. these correspond to the bodytemplate 3 for echo devices with displays. it would be nice if you could also set the bodytemplate for skills that also appear on smartphones displays. if you try to include the bodytemplates in the code the skill crashes in the alexa app.
to get it to the point. the function "card.renderer()" is automatically set to bodytemplate3. The developer should have the possibility to decide in which template format the photos should appear on the app with the function card.renderer().
