For example, if your activity is on and the TV is off (it wasn't turned on because of the state confusion), you can click fix power which will let off become green. (If it is currently green, pls click power twice) to inform that the current device is in shutdown state, and then you can go back to the activity page to switch to other activities, and it will operate normally.
If you think it is too hard to remember, suggest not use fix function to fix the power state. The purpose of fixing power is to keep the actual state of the device consistent with the state displayed by the Activity. You can press the off key to close all the Activities first, and if there is a device open, close it manually in device mode.
At this point, all the states are the same, and there will be no conflict when you open the activity.
