Hi @Ristéard,
Thank you for sharing your report about this and welcome to the Roku Community!
It seems like we've got some complicated issues here. Does this navigation issue occur as well the same as using the Roku mobile app remote?
In addition, when you see the issue occur on YouTube does a simple restart help, or does it come back right after the reset?
Please tell us more about this so that we can further assist you.
Thanks,
Rey
