tapping `Switch to the free model` doesn't do anything (need to tap `Retry`)

[kjozwiak]

Description

Tapping on Switch to the free model doesn't do anything. Once you tap on Switch to the free model, you'll instantly see a Retry button appear in it's place. Tapping on the Retry button correctly switches the user to LLama 2 13b as expected.

Steps to reproduce

Note: This assumes that you've already gone through onboarding and have hit the rate limit

1. once you've reached a rate limit on either Mixtral or Calude Instant, ensure that the upsell UI is visible
2. tap on Switch to the free model and notice that it will be replayed with a Retry button (nothing happens the first time around)
3. tap on Retry and you'll know be switched to LLama 2 13b

Actual result

Expected result

Tapping on Switch to the free model should switch the user to LLama 2 13b without the need to tap on Retry (unless it failed).
