I appreciate your advice, Anton. However, the issue I'm having isn't with uploading a custom template. The problem is that when I try to create an invoice from an estimate, my custom template doesn't load properly - all my customizations are removed (font, layout, logo). I've been using my custom template for about two years problem-free until about 5 weeks ago. It seems like either QBs pushed an update that broke something or the issue is specific to my account. My custom invoice template works when I create a brand new invoice that isn't connected to an estimate.
