Stockback™ is always on and cannot be turned off.

If you have not selected a Portfolio for your Stockback™ to be invested in, your Stockback™ will continue to accumulate and you can just leave it be. Stockback™ that has been left to accumulate cannot be withdrawn unless it is invested into a Portfolio first.

If you have selected a Portfolio and want your Stockback™ to stop being automatically invested into your Portfolio, unfortunately at this stage you won't be able to do this.

As an alternative, you may choose to sell the Portfolio holdings created by your Stockback™ rewards and withdraw the resulting funds from your US Wallet.
