My Question or Issue

The car multimedia does not display the entire APP home screen in full, displaying only the first 2 buttons (sign up for free and continue with facebook) and the log in button is not displayed.
Unfortunately the continue button with facebook does not work properly and therefore I can not access my account and I can not create a new one because the email is already registered.
Please can you help me with any option or release an update with the buttons being displayed in the middle of the screen rather than displayed at the end?

Thank you,
Phill
