"An option of a function in Parental Control that blocks ticked contents such as sex violence while still allowing kids to play their games online" should be available. Perhaps just need a little bit of modifications in Parental Control?
We would like to know more details regarding your suggested idea.
We would also like to know how is your Parental Control configured?
Would you mind if we ask you to try checking the settings or configuration of the Parental Control?
Regarding your concern, we actually have different settings that you may want to look into.
First, the Website Filter Rules. This setting can be configured to modify which content you wish your children can view when they try to access the internet.
Second is the Program Controls. This setting is to prevent your child from opening specific programs at certain times. Use this feature to block chat programs or games when your kids should be using the Internet for homework. You can still open these programs at any time by providing your password.
You may read more about the configuration of the Parental Controls on this link below.
