Ok, I found his transaction myself.
As you see in screenshot in his post, transaction ends up with 1397aec065df4f:

This is completed transaction on Mainnet (executed about 8 hours ago): https://etherscan.io/tx/0xb065ecdf776aaf4b42930019c96a385bce1d3621ce99886d42c799a41e2423ba
Probably, the person who wrote this article does not know how cross-chain bridges and AMB work, and why the funds go to the zero address when sent to another network - I recommend him to better understand this topic. Apparently, the relayer did not allocate enough commission for the transaction, and therefore it took so long, and he thought that the funds were gone. I ask the one who has contact with him to send him a link to this message and ask him to remove the article containing incorrect information, or add a refutation.
