Your place alerts are closely correlated to your location accuracy, as well as the location accuracy of your friend's. Please note that location accuracy depends on many factors, such as your environment and your phone. The notification can be delayed up to 15 minutes depending on the battery status or signal strength.
When you're experiencing delayed notifications, please check the following:
- Check that the location settings(GPS) and Wi-Fi are both on
- Check whether the place is registered correctly. If the range of notification is too small, you may need to increase the radius.
- iSharing > Menu(top left) > Place notification > select a friend > select a place > adjust range > save
