Week Core Factory Reset Mobdro

I’m a newbie on this forum so apologies if it’s in the incorrect category.

I had to do a Factory Reset on my Wetek Core box. All went to plan with the exception that the Mobdro add-on no longer opens. I downloaded the app via Aptoid and can open it via Settings/Apps but not from the shortcut in the home screen

How can I link the shortcut to the App or alternatively add Apps to the start screen?

TIA
