When Turn ON the restrict mature and uncategorised, it blocks not only mature content but also uncategorised that are safe.
I know why you might want to block uncategorised, but wouldn't it be better to separate out those two options
aka the ability tp block 'mature' but not uncategorised.
As it stands the feature block a lot of videos that the video produces had failed to simply categorize
we have the same issue!
This is not something we currently have the ability to do but I will add it to the feedback lists we keep for our developers to look at for future implementation.
