Do I need to set up a tax override for each EU country in the IOSS system?

Hi there community! I am having such a nightmare with this ‘simplified’ IOSS system which i have now set up for my company. What i would love a simple yes/no answer is whether i now need to set up a tax override per EU country based on the countrys own tax rate (e.d. Sweden 22% for example). And if so, does this mean buyers from those countries are being charged their local tax rate on checkout?

I am UK business selling goods to the EU and just want to make sure i am charging the correct tax etc.

did you manage to set it up with the new Shopify IOSS tax configureation options?
