I get a gray screen when I login on other computer.

I have been using TeamViewer to remotely share my mother's computer screen for some time.  She has an iMac and I have a MacBook Pro.  Both are running the latest version of macOS and TeamViewer.  However, in the last few months, TeamViewer has stopped working properly for us.  When I login to her computer, I can see her menu bar, at the top of the window, but the rest of her screen is just gray.  I cannot see any of here windows, desctop, etc.  Other than the menu bar, I can see nothing of what is on her screen.  As an experiment, I tried to share my screen with her and she had the same result.

If I deselect "Remove Wallpaper" in the View menu, then I can see her desktop picture, but I still can't see any of the open windows or icons on her desktop.

On the other hand, I do not have this problem when I use TeamViewer to login to my office computer.  It's running Windows 10.

So, can anyone tell me what is going wrong with my connection to my mother's commputer?

I found the solution while helping my mother install a different program that is also capable of screen sharing.

1. Open System Preferences.
2. Click on Security & Privacy.
3. Click on the Privacy tab.
4. In the pain on the left, scroll down to  and select Screen Recording.
5. Click the check box next to TeamViewer.

Once you have done this, TeamViewer will be able to see and share the screen of the that computer.
