Why are there no missions showing up?

Things to try: 

1. Check your device’s connection to ensure you have network coverage.
2. Ensure you have hit the SEARCH THIS AREA button until it shows ALL LOADED. 
3. Still no missions? They might have already been completed in your area but hold tight; there is always more to come!

OR If you think lacking missions is an error with the app, report an issue through the Menu tab.
