It's been brought up before with a generic response. Us parents would like to set a locking sleep timer to shut down the roku device that requires a pin or password to reset. Many of us have children that abuse screen time sneaking on all hours of the night, depriving themselves of valued sleep. I'd like my children's devices to lock at 9pm school nights, until 7am the following morning. I'd also like to block specific content on their devices in a parental control setting. It's as simple as adding parental control in settings in the device that control content and screen time and creating a pin to access them. That, or a remote lock down in my phone app that doesn't allow them access.
