[Bug]: Other Model provider aren't blocked on mobile after starting a chat

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/mobile

Steps to reproduce

1. Open the app.
2. Start a thread/chat
3. Send a message with any model, e.g Claude
4. Switch to a model from a different provider, e.g gpt 5.6
5. You can see that its not blocked like on pc version, it's just throwing an error

Expected behavior

After starting a chat with a provider (claude in this screen), the other (openai in this example) should be blocked or removed from the list.

Not like right now, it only does remove it (just realized while doing the screen) after the error was throwed

And as you can see, the menu is weirdly placed 😂

Actual behavior

We can switch from anthropic to openai and vice versa without the other being removed/blocked from the list like on web/app

Thanks for the report. We believe this is fixed by PR #5625.

The mobile thread-settings sheet now filters model choices to the provider instance already used by the thread. A Claude thread should no longer allow a Codex model to be selected and sent to the server.

I'm closing this as fixed as part of an automated pass on all open issues. If this still happens in a mobile build that includes PR #5625, please reply with the mobile version, thread provider, and model shown in the sheet, and we can reopen it.
