In-app purchase not working – TrailLink: Bike, Run, Walk Review

Tried to make a purchase of credits to download a map on 05/21/2017. My credit card was charged, but received $0.00 credit within the app to be able to make the map purchase to download and use. Update: 08/25/2017 I have received map credit from my original review. I have not tried to use or download any maps since receiving credits. I finally tried to download a map again and now I get an error message that won't allow me to download. This APP certainly has potential, but the lack of support from the app itself and not working properly makes it useless. I would not suggest this APP to anyone.
