How to Set a Default App for the LINK Tile
You can set a default app for the LINK tile so that whenever you open LINK, it will immediately open the app of your choice.
Open LINK and tap on the gear at the bottom right of the screen.
Tap into the default app field - you will see a list of all available apps. Select the app you wish the LINK tile to default to.
Tap the home key and then swipe out of LINK.
When you return to LINK it will immediately open the default app that you selected previously.
