It's a decent app, it does what it needs to. However, to receive order offers as they appear, and not miss any offers, I HAVE to leave my phone open and unlocked the whole time I'm waiting on order offer, regardless of when I'm scheduled to work. When I complained to Shopper Support they told me "this does not indicate a problem with the app". This is the only app on my phone with a "delayed notification", which tells me this is a feature, not a bug. They only care about the client$.
