Hi, @Elmer_J_Fudd
Welcome!
I understand your concern regarding the issue you have encountered with the France Channel app that doesn't save favorites, and I'm here to refer you to the right support so the issue will be addressed.
For this matter, I recommend contacting the France Channel support and sharing your concern with them. It is important to note that most apps on Roku are directly managed by their respective channel providers. Once you report any issues with their app, they can provide you with a workaround or create an update to resolve the issue.
To contact them, you can refer to France Channel
Hope this helps, and keep us posted on what you find out.
Thanks,
Roku Community Team.
