Hi Tillyandmo, thank you for posting to bring this to our attention!
Thank you to the community for offering advice and support.
It is true to say that the PIN cannot be removed - can I just check it was not continuously interrupting the film asking for the PIN? It may ask for you to input this twice (once before and once after selecting the content) but it should not be more than this.
Let us know if there is anything else we can help with! All the best.
Molly
