[Changing background on phone with Kid Safe]

I am not sure what most of that information has to do with my question. I have a Samsung Samsung Galaxy S7 and he has a Motorola Moto e5. Neither have problems with storage and his is new. The notification is being sent. With other notifications I was able to go into my desk top application and allow permission for the app or access to settings or whatever. There is a notification for the fact he tried to change the background picture and there is a button for me to click to give him access. I click the button and nothing happens. The box disappears from the screen. On my devise there is a section that appears to be where I can grant permission for things but nothing comes into that part of my mobile app. I I have to go into my desktop to grant permission through the notification section. I just want him to be able to change the background picture to his phone. Not too complicated.

[Changing background on phone with Kid Safe]

I just downloaded the kid safe app on my phone and my sons phone today. Navigating it has been fairly easy but there is one thing I cannot figure out. On his phone I tried to change the wallpaper on the phone. It said that he didnt have access and he had to ask for permission so I clicked that button. On my phone it says there are no current requests. It has been 3 hours. My notification says that he tried to access a feature that was restricted but it does not give me the ability to grant the phone access. I already granted access for "settings" on the phone which should include the wallpaper. Anyone have suggestions?
