Klaviyo: Email Marketing & SMS

I hate the Klaviyo app. I was forced to switch over to it when I hired an email marketing team last year and I wish I never left Omnisend. Klaviyo requires you to be an expert on their platform in order to be able to use it. I've been trying to modify a basic ORDER CONFIRMATION email, I just need it to show the variants of the products ordered, the prices, shipping, tax and total.. but it's so difficult to do!!! It shouldn't be so difficult to make a basic order confirmation email show the items ordered and the total paid... I will be leaving Klaviyo as soon as I can figure out how to migrate all my existing flows to a better platform.
