Hi @ReymondO  I appreciate your help, however, I have tried what you suggested where I go into incognito mode to update my email and I have also tried Microsoft Edge browser instead of my usual Google Chrome and I've even attempted to create an invoice on my app on my Iphone 13Max, and nothing I seem to try is updating my invoices to reflect my current email address of [email address removed]. Every invoice I've tried creating still shows my last email of [email address removed]. I don't know what else to try and I don't understand why the program doesn't allow me to manually update my email address on the invoice? 

I'm hoping you can help as being able to create invoices is the primary reason for having Quickbooks. 

Thanks much, 

Josh
