After I checkout, i found on order that customer_is_guest = 1 although I logged in before,
I debug and found on file vendor/collector-bank/collector-checkout-magento2/src/QuoteUpdater.php line $quote->setCustomerIsGuest(true);
called from file vendor/collector-bank/collector-checkout-magento2/src/Controller/Validation/Index.php line $quote = $this->quoteUpdater->setQuoteData($quote, $checkoutData, .
If calling from remote to validate, I sure that customer session will not existed
