Due to modifications in system permissions by certain smartphone brands, some OPPO devices may encounter issues with enabling the "Allow pop-ups in the background" setting (known to occur on OPPO Reno 12F with Android 15). Specifically, after completing the AirDroid Kids device binding, attempting to enable the "Allow pop-ups in the background" option and clicking "Settings" results in the automatic redirect page not displaying the option.
In such cases, please manually navigate to the phone's system settings > Apps > Special app access > Display pop-ups while in background, locate the AirDroid Kids app, and enable the "Display pop-ups while in background" option.
