If your app crashes, try these steps to get it going again:
Select the menu icon in the top left corner of your app.
Go to “SETTINGS” -> “DISPLAY AND BRIGHTNESS” and make sure that the Auto-lock screen setting is set to “NEVER.”
Logout, this should then show you the login page, where you can enter your username and password.
To force close the app: double click “HOME” (the circular button below the screen) button and then swipe the Uber Eats app upwards.
To perform a hard reset: Press and hold the “HOME” and “STANDBY” buttons (at the top of the iPad). Keep them held for approximately 10-12 seconds until device restarts and you see the Apple logo.
Open your Uber Eats app and login using your login details.
