Open the Zopa app and head to your Smart Savings Hub. From there, click the Next auto-save button. You'll see the option to adjust your auto-save, where you can change how much you’d like to save and into which pots. You can then choose whether to apply this change to your next auto-save only, or to all future auto-saves. If you choose to change all future auto-saves, you can also review the date your auto-save is taken as well as the account it’s taken from.  

And if you ever decide that you no longer want to use auto-save, you can cancel it at any time in the app.
