9 times out of 10 if your icon is not appearing it means your phone's GPS settings are not correct. Double check these settings:

• Give web page permission. When the GPS loaded, you were probably prompted asking whether to allow MazeGPS.com access to use your position. On most devices this can be updated via an icon in the menu bar.
• Make sure your device GPS is on. On most Android devices, slide down from the top of the screen to expose your GPS button. On iPhone, from the home screen go to Settings > Privacy > Location Services.
• Enable High Accuracy GPS. Android supports choosing a power saving mode for GPS that only uses cell towers and not your GPS. This mode saves power but is not accurate to see you moving. Slide down and hold the GPS button or go to Device Settings>More>Location. Once there make sure the Mode is set to High Accuracy

If you make any of the above changes and still do not see a result, refresh your page.
