Expreem it’s about location around you, if you don’t give us the permission to use your current location we can’t help you finding cool things to do near you. If you have refused to the permission you will be stuck in a temporary page until you go to your iphone settings:
settings > privacy > location and enable expreem to use your location.
Once you have done it, you just go back to open expreem app and it will let you walk inside.
