Why is the shortcut of my app not updated when I put a new one?

I entered a new shortcut to my app and it is not updated on my cell phone, the first shortcut I used was custom and I changed it to a default one, and this is not reflected when adding a shortcut to my cell phone.

Thank you very much to all!

Uninstall and install Appsheet from my cell phone and when I generated the shortcut of my app again, the problem was corrected!
