I purchased the module and installed its version 1.0.6 on my site Magento 2.2.4.
After applying the gift code to the checkout page, the page got stuck on loading and the payment summary not update.
Do you have a fix available?
The issue happened since the class Magento\Quote\Model\MaskedQuoteIdToQuoteIdInterface does not exist on M2.2.x.
To fix this error, please edit file app/code/Bss/GiftCard/Model/GiftCard.php as below:
