The client reported that messages from the Cross selling scenario are empty - I checked, and it looks like there is nothing in some blocks - that was a test message but in some blocks the products were visible.

Moreover, the client reported that their customers received an empty messages.

I’ve checked this and for example this product: https://ispot.pl/b-safe-silicon-case-pink-etui-dla-iphone-se-2-gen-8-7?from=listing&campaign-id=20&header=Etui+dla%20iPhone%20SE%202.%20i%203.%20generacji/8/7/6s/6

and it's out of stock but the client said that their customers received an empty messages so do we blocked messages where the products are out of stock?
