## Review summary

Users overwhelmingly report sign-in problems with PrepFE. The majority of reviews describe the sign-in button not responding or doing nothing, preventing access after subscribing. Several also note the on-screen keyboard obscures the username and password fields, making input hard or impossible to complete. Collectively, the sign-in flow is broken, with users unable to log in or reach the course content despite paying for a multi-month membership. A few mentions reference a fake button or account creation errors, but the core issue is consistent: the login process is non-functional across devices.

### Cons

- Sign-in button is unresponsive / does nothing when tapped.
- Keyboard covers login fields, obscuring username/password inputs.
- Cannot sign in / login flow is broken, preventing access after entering credentials.
