Email feature on invoice (custom domain)

Hi guys, please help. I am usually using the obsolete pdf generator feature for emailing my client invoices. Since it’s getting obsolete, I am trying the regular feature for emailing invoices or statement, however, upon checking the email and by clicking the link, it’s showing my manager domain, instead of my custom domain.

Thanks.


Not sure how you managed to still use custom domains see post:

my custom domain still works fine.
