NO NOTIFICATIONS if phone is idle. Battery saver is off. Very frustrating to have cold food I didn't know arrived. It's been happening for over a year. I don't have this problem with other apps. FIX YOUR APP UBER. On another note, I wish you'd pay your drivers reasonably. Fees keep going up but I never know if I'm tipping too much or too little (and wouldn't it be great if they didn't need those tips to survive). Pricing transparency would be nice.
