Hello happy members - unfortunate one with Paypal processing like me

After many tests, it seem the current documentation from odoo that suggest to call SHOP/CONFIRMATION after PAYPAL PAYMENT is wrong

the page to be called about after a paypal payment is SHOP/PAYMENT/VALIDATE - then you will see that 

- the Cart is cleared

- a new order is initialized for new shopping

but then you get following additionnal issues :

- the cancel process from paypal return you into the shop, (order not cleared) but can't be paid with changes in cart

- the order stay in Draft state

- The payment stay in Draft state

- no mail is sent to the buyer,as it should be to confirm the payment

Best regards
