Why didn’t I receive a notification alerting me that my Green P Mobile Pay time is about to expire?

Like many apps or mobile services, Green P Mobile Pay requires a good cellular or Wi-Fi signal. Check your phone’s coverage status and/or Wi-Fi signal. We cannot be responsible for any failure to get a notification alert or extend parking because of failures in wireless service or due to failure or malfunctions with your wireless carrier. Please ensure you are receiving Push notifications from the app in your phone settings.
