Parental control PIN settings do NOT block unrated!!
I'm incredibly frustrated with ROKUs terrible parental controls! I intentionally set a PIN as required for all content on the ROKU Channel above PG (as i find much of the stuff rated 14+ to be inappropriate for my young teens to watch unsupervised)... but ive tested it out by searching mature-themed search terms and the ROKU channel still allows them to find AND WATCH "un rated" content WITHOUT the PIN being required! This is absolutely unacceptable!
I wanted to post this here in case other parents are not aware of this loophole in the parental controls.
- Thanks for reaching out about the parental controls — happy to help. - Roku Channel parental controls are PIN-based and only work when you're signed in to The Roku Channel. Once set up, a PIN is required to watch content with certain ratings, based on the level you choose. - These ratings follow standard systems like the MPAA for movies and TV Parental Guidelines in the U.S. (You can check out more details here: Movie Ratings | TV Ratings). Other countries have similar systems, too. - Hope that clears things up! Let us know if you have more questions. 
 Thanks,
