Hi @JohnLennon, welcome to the community.
Do you mean the shortcuts have disappeared from your home screen?
If you press the apps button on the home screen, you should see a list of all your installed applications.
If you do not see them all here, press the 3 dots on the top right and choose Sort Apps > By Name.
When you see the app you want to add to your home screen, tap and hold on it then drag it to the home screen.
