This wasn't happening on my iP5 when I updated to 8 but since I got my 6+, I keep getting popup notifications when I wake the phone up about various apps that are using location services in the background. If you follow the "settings" prompt, it just takes you to the location services setting where the app can be set to ALWAYS or NEVER. Well yeah, I know I have LS enabled for these apps. I can't figure out how to disable this message or why it suddenly started happening. It's worth noting that it's notifying me of apps that I've recently used and those that haven't been used in weeks. Also background refresh is off. Anyone else getting this?
