I found more issues with the extension in Magento 2.4.4 / PHP 8.1 with version 1.3.9.
See attached. ‘Add to cart’ and ‘Proceed to checkout’ buttons don’t work.
Can you please fix it?
The current version 1.3.9 is not compatible well with M2.4.4 at this time.
To solve it, please edit/overwrite this file app/code/Bss/FastOrder/Helper/Cart.php
Please apply the change on the site.
If you have any issues, please feel free to contact us.
We'd like to help.
