Not working on iPhone5

Was a great app for 3 years. Now, wont work on iPhone5. Keeps asking me to enable background app refresh (which is enabled, generally), but there is no option to specifically enable background app refresh for this app - its not listed. So, I cant use the app at all. Same with Map My Hike. They need to fix this.
