To say that this is frustrating is an understatement. It's not frustrating, it immediately disqualifies you from being used even by a tiny business that has products in more than one tax category. Applying different tax rates per different products is so extremely basic in all of the EU, my only conclusion is that you don't care about customers outside US and Canada. Seeing this being still a problem in 2023 is a testament to this. I really love all the website features you provide, but we simply cannot use square space without this, and will need to look elsewhere.
Consider all the other features available at your platform, this is extremely simple to implement from an engineering and design perspective, so I'm really curious what has stopped you from implementing this for 2.5 years.
