For those of you who may be wondering why Rokagram no longer works, it's because Instagram no longer allows use of their API except for a few narrowly defined use cases. On June 1, they started enforcing this policy which means the Rokagram channel (of which I am the developer) really has not way to work. Definitely a bummer, but there is not much I can do about it. If you're interested, there are links to read more at http://rokagram.com and https://www.reddit.com/r/Roku/comments/4nd3go/roku_users_staff_please_help_get_rokagram_back_on/
If anything changes, I'll post an update.
