Shopify dynamic "Buy now" buttons have certain limitations, so we toggle the visibility of this button to prevent user errors.
In this specific scenario, Shopify dynamic buttons do not support "multi-variants" in a single add-to-cart request. Therefore, we automatically hide the "Buy now" button when bundles have variants enabled, and the customer selects different variants in the quantity deal (for example, two different variants in a 2-quantity deal).
Is there any workarounds for this?
Currently, there are no workarounds available. Shopify does not support multi-variants for the "Buy now" button, and we have no control over this behavior.
