I have Crave subscription included with my Bell Expressvu programming in Canada. When I use the Crave app on my Roku TV, I do not get an option to login with my provider credentials, as I can on every other smart device I own. The only option on Roku is to sign up for a new subscription. Is there is no ability to access my existing Crave account on Roku ??
Are you using the Crave app or trying to access it through "The Roku Channel" app?

Using the Crave app. No-where do I see a provision to login to existing account or thru a provider.
I'd try it myself, but that's one of those apps that's only available in Canada. Maybe try contacting Crave:
