Hi frank-ofegroup-c,
Thank you for reaching out to us.
As long as you have selected the option Automatically update super rates on your Payroll Settings, it will automatically update every time a change is made to the super rate. Can we try to click Actions > Recalculate, or you may delete and recreate the pay run if it has not been finalise yet.
I hope this helps. If still it doesn’t work, I'd highly suggest you contacting our QuickBooks Online Support via Chat or Phone Support Hotline on this link so they can check further: https://help.quickbooks.intuit.com/en_AU/contact
