How do I delete or edit a bundle on the Mobile App?

From the Wallet View, switch to the Bundle you want to edit or delete from the top left drop-down menu. 

Once the bundle is selected, select the edit icon (pencil) next to the Bundle to edit it. 

This will open a new menu from which you can edit the name of the bundle, update the appearance of the bundle or edit the addresses that are part of that bundle. 

If you want to delete that bundle, you can do so by clicking on the delete icon (garbage can) at the top right.
