How to fix incorrect EU VAT rates on international groceries?

[Shivam_Parikh]

We are selling International Groceries online in Germany which means our VAT is 5% (Usually 7% but because of Covid its at 5%). However once I updated to the new EU VAT System all my products got changed to 16% and now my customers are being charged 16% VAT rather than 5%. This is a 11% increase and not at all profitable. 

There is no way to change the default tax rate and its very annoying. 

The only solution given to me by Shopify Support is to create a Tax Override but the Tax Override only words on Manual Collections; so now they expect me to make a manual collection with all products and keep updating it manually? 

There has to be another solution or an app for this.
