Can anyone advise on what I can do to fix this please?
It was not possible to generate the label. Service not available for the delivery or dispatch from address postcode.
I've printed two labels this morning fine and then I cannot print my last one as this error in a red box keeps showing - there seems no issues with the address for either of us so have no idea, all I know is that I need to post it but can't print the label or even generate a QR code?
