[Bug]: Authentication switching issues on codex

Before submitting

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

Area

Not sure

Steps to reproduce

1- authenticate to another account on codex.
2- in settings it displays that the account has been authenticated successfully
3- continue with chat and see that it is still running on old account since we get error that limits have been used up and the new accounts does not have issues
4- restart t3 and session is updated and new authenticated account works fine.

Expected behavior

Changing the authenticated account should automatically use the new authenticated account for new messages withought having to restart t3 for the new authenticated account to work.

Actual behavior

Unless you restart t3 the switched authenticated account does not take place and work when continuing chat threads that where on the old account.

Impact

Major degradation or frequent failure

Workaround

No response

Start by reproducing the account switch from Settings, then continue an existing chat without restarting t3 and compare it with the restarted session. Trace how the authenticated account is used for new messages and consider the behavior fixed when switching accounts immediately affects continued chats without a restart.
