@Jasper-ketelaar I am unable to re-produce the same, just to rewind

• I added items to cart from frontend
• Deleted items one by one using API V1/carts/{quote_id}/items/{item_id}
• Checked back using V1/carts/{quote_id}

This leads to "items_count": 0, "items_qty": 0 so Please share exact steps to re-produce.

@Jasper-ketelaar i was trying to reproduce this issue on 2.3.3 and 2.4 version many times but I did not succeed.
For work with api i was using Postman.

My reproduce flow:

1. Created new quote: POST /V1/carts/mine
2. Added couple of items to quote (with configurable products) POST /V1/carts/{quoteId}/items
   2.1 My request body example:

{
  "cartItem": {
    "sku": "WS12",
    "qty": 1,
    "quote_id": "{quoteId}",
    "product_option": {
    	"extension_attributes": {
    		"configurable_item_options":
    		[
    			{
    				"option_id": "152",
    				"option_value": 166
    				
    			},
    			{
    				"option_id": "93",
    				"option_value": 57
    			}
    		]
    	}
    }
  }
}

3. Checked state of quote and made sure everything with quote is ok (item_qty is right). GET /V1/carts/{quoteId
4. Deleted all items one by one DELETE /V1/{quoteId}/5/items/{itemId}
5. Checked state of quote again and made sure that item_qty is correct

After that i also wrote some script that do this many times and very fast, and i never got the wrong result.

So could you give more detailed information ? For example php version, work environment configs or maybe you use some extension which has side effects related to quote?
