If you use the city's new pay-by-phone parking meter app, don't be surprised if a ticket arrives in the mail.
It's because hundreds of drivers who use the app have been wrongly ticketed.
City officials started rolling out the new Park Chicago app in may.
Since then, DNA Info reports more than 300 drivers have received tickets for an expired-meter violation, even though there was still time on the meter.
A time gap between payment and a database update is to blame.
Officials say only a small percentage of people who used the app have gotten tickets but did not specify how many times the app has been used overall to pay for meters.
