unable to remove this app tried with mobile app to remove and also a factory reset not sure what the issue is
If you have an active subscription through Roku you won't be able to remote the app. You can manage your subscriptions that are through Roku at https://my.roku.com .
does that also count for free subscriptions once that is done will I be able to remove it?
If by "free subscriptions" you mean a free trial that will charge you the regular rate when the trial ends...
BEFORE THE FREE TRIAL EXPIRES -- Highlight the channel in the channel grid, press the * key on your remote, click on Manage Subcriptions, and cancel automatic payments (I don't have a subscription through Roku to check the exact wording). If you don't do this before you are first charged, you'll have to wait until the pre-paid period ends in order to remove the channel.
