        return $this;

}
}

Screen shot ref https://nimb.ws/qSPujg

The subtotal does not change on the cart and also in the window.checkoutConfig.quoteData.base_grand_total

eg

A product $40

B product $20 // removed

subtotal $60 //remains same - after a refresh , even go to checkout

Any suggestion?

Answer 1

Try to add $currentQuote->setTriggerRecollect(1); before your collectTotals().

It will be :

$currentQuote->setTriggerRecollect(1);
$currentQuote->collectTotals()->save();

Answer 2

If above code doesn't work then use below as well.

$currentQuote= $this->_checkoutSession->getQuote();

$shippingAddress = $currentQuote->getShippingAddress();

$shippingAddress->setCollectShippingRates(true)->collectShippingRates();

$currentQuote->setTriggerRecollect(1);

$currentQuote->collectTotals();

$currentQuote->save($currentQuote);
