I noticed the same thing. In the app, normal “Chat” threads are only available via a “Checking recent chats” window, while projects, GPTs, library… are completely absent.

The web version of ChatGPT is confusing too. Now it has separate “Chat” and “Work” tabs (what about a Codex tab?), and it shifts the burden on the user to know when to use one or the other. Note that using the “Work” tab means using Codex usage limits [^1], but that’s hidden away in the settings.

Also, apparently “GPT-5.6 Terra and GPT-5.6 Luna are not selectable in standard ChatGPT conversations” [^2] — so if you want to use these models, you must go to the Work tab or download the app.

I don’t understand why there is so much fragmentation in what was supposed to be a unified app. The way that it is now, it’s far from intuitive.
