Thanks so much for posting your inquiry in the community. The Crave profiles are only available via the Crave app/website. There is no specific Crave app for the Ignite TV platform so there is no option to select any of the profiles available via the app.
Crave content is available on Ignite TV via the Crave live TV channels and Crave on-demand. This usage is tracked separately from the app/website interface.
