When I was working in a queue feature (for example to buy tailor swift ticket), and was proud of my complicated real-time solution using websockets and CRDTs...then a more experienced guy came, rearchitected in a much simpler way using just the DB with long-polling, not real real-time (but who cares), and it ended up simpler to deal with network splits or crashes. Learned the hard way you can never rely on the network if you require consistency, and it's also often simpler code-wise.
