I generally prefer to subscribe to channels directly on their websites rather than through a 3rd party like Roku. That way your account is with the channel, not the 3rd party, and it eliminates lots of login problems and confusion, and limits mutual finger pointing when there are problems.
It will also enable you to view that service on any platform that the channel service supports (computer, dedicated app on phone or tablet, dedicated app on various streaming devices, etc.), not just on the 3rd party through which you may have subscribed before -- just log into the service's app using the credentials you established with the service.
Edit: And by the way, I've been subscribed directly with Acorn for a couple of years now, viewing via the Roku Acorn app, with zero problems.
