Easy! You can make this change right from the Starship app! Simply follow the instructions below.
Note: There are restrictions on how often you may change your bank (ex. there can be no pending transactions and a linked bank may only be changed once every 30 days). If you receive an error, please try again later.
Tap on the profile button in the upper right corner
Tap on the Linked Bank that is currently connected
Tap Change Bank
That's it 😃
