Ask HN: Why am I getting a different HN home page on my phone?

Right now on my phone, the entire home page is different than on my MacBook on the same network.

For example item 14 is about Bluesky but on my MacBook it’s about linoleic acid.

Item 1 on my phone is “using the railway network” while on MacBook it’s “foundational refinement proofs”

Why is it so wildly different on the same network? It’s a completely different list of articles.
