TCL TV
If you are using a TCL TV then you need to enable auto launch permission using the preinstalled app called "Safety Guard". Otherwise tvusage cannot launch itself after tv restart.
Safety Guard -> Permission Shield -> Auto Launch -> Auto Manager: Closed; tvusage: Opened
If it does not help then you may need to uninstall Safety Guard app. Incase if you need more details then please contact support@tvusage.app
