Open Elevault and tap the menu to open it. It looks like three blue lines in the top left corner of the app.
Tap Linked Accounts.
Select the linked bank account you would like to remove.
Tap Unlink this Account and confirm your selection by tapping Unlink from the pop-up alert.
You'll be returned to the Linked Accounts screen. Here, you can tap Cancelled Linked Accounts to review any past accounts that have since been unlinked.
Unlinked accounts can be used again; however, you must go through the linked accounts process again as if you are linking a new bank account.
