@dshan & @nikhiljdhv – The Cart and Checkout blocks are still only previews, so development is still underway. If you’d like to keep an eye our on issues related to these specific payment gateways being added, I’d suggest watching out on the GitHub repository: https://github.com/woocommerce/woocommerce-gutenberg-products-block/issues
At this time, I’m unable to provide a timeline for any additional payment gateways. If you’d like to create an issue for added support for your payment gateways, feel free. Be sure to include all of the required information, including details as to why these should be prioritized.
I am not a developer, so I’m not making any assumptions as to if/when some payment gateway support will be added.
I’m going to go ahead and set this to Resolved though, as it’s not so much an issue as it is a feature request.
Thanks!
– Joey
