Hi LieraMarie_A
Thank you for your feedback. I do not think this is a browser issue but I did try your suggestions but it did not work. I did some further testing on when the invoices fail to add to the credit note and I did pick up a trend where there is a non monetary/product line item in the invoice itself then it fails to add to credit note. Can that perhaps be a valid reason for the failure?
Looking forward to your feedback.
