Disappearing APP logos from Home Screens

Tech guy here! You may have a setting enabled called "Offload Unused Apps" enabled. This allows the iPhone to save storage/run faster by not having apps running in the background. Of course, let's check to see if it's enabled

1. From the Home screen, launch the Settings app.
2. Select iTunes & App Store.
3. Scroll down to and select Offload Unused Apps. If the switch indicator is green, it means it’s ON, toggle the switch to turn it OFF.

"Disappearing APP logos from Home Screens: On my iPhone XS iOS 15.5 my WALLET app logo no longer displays on my home screen and I have to access the app using the SEARCH feature The same condition for the SETTINGs app and CALENDAR app. Is this happening to anyone else?"

No. I am not having this issue.

Reset the Home Screen Layout:

If widgets are not working as they should or have gone missing somehow, then you need to reset the Home Screen Layout...

Go Here: Move and Organize Apps on iPhone - Apple Support

You'd have to add back all the widgets that you can recall being back on there. So, write down what is currently on the Home Screen.

Scroll to: Reset the Home Screen and Apps to their Original Layout

1. Go to: Settings
2. Tap: General
3. Tap: Reset
4. Tap: Reset Home Screen Layout
5. Then... Add the apps back

Oh! So I checked again and when it means to offload, it uninstalls the app. So you would have to reinstall the app to have it back on the iPhone.

Since you turned off the setting, you will not have that issue anymore
