I have a TCL Roku TV and an active Britbox on Roku subscription. Yesterday, all Britbox programs have stopped responding to clicks of the remote.
There is no connection problem and no other channels seem to be affected.
Since you say your Britbox subscription is through Roku...
When you highlight the channel in your channel grid and press the * button on your Roku remote, "Remove channel" will be replaced by "Manage subscriptions". Click this and follow the prompts to unsubscribe from this channel. (Don't worry. You'll still have use of it for the balance of your pre-paid subscription period. You can resubscribe later if you like.) Now the "Remove channel" menu item will be back and you can remove the channel.
Now restart your Roku and reinstall the channel.
There is no unsubscribe option, there is only “manage subscription” which only allows you to resubscribe , I’m having the same issue with the viaplay Roku channel.
