Display customizations stop working with new checkout

-- HikaShop version -- : 3.4.0
-- Joomla version -- : 3.8.6
-- PHP version -- : 7

We've recently updated to Hikashop 3.4.0 and tried using the new checkout (disabled the legacy version). However, upon doing so our customizations on the checkout login view were reset. Is there a new place to add customizations with the new checkout?

Hello,

Your customization haven't be removed.
The new checkout system is using new views so we do not generate incompatibility with old view of the legacy checkout.
You'll find all new checkout views under "show_block_..."

Regards,
