Just received this message from Uber:
UBER] we notice that you may have left your partner app running whilst you were away from your vehicle, and therefore have been unable to accept requests. In order to provide a great service to riders, being online with the Uber app means being willing to accept and complete trips. From today, if you miss two trip requests in a row we will take this as an indication you are unavailable, and we will log you off the system for 10 minutes. If you change your mind and want to go back online, you will be able to do so after 10 minutes.
