After upgrade of S/4HANA application from 1511 to 1610, we had few of our SAP standard Fiori apps choking.
Errors were different. Below are the steps we followed to fix “Cannot load tile”.
Edit home page:
Delete the tile:
Open app finder from the same screen:
Now you jump to the screen from where you can add the tiles you need.
Pin the tiles which you need.
Now go back to the home screen and see if you have the apps you need back on the screen.
