Even now in 2017 I still get prompts for apps that want to use my location constantly and multiple times from the same app after I've told it "yes use my location" three others times. Things like this make me want to switch to android. I don't want my phone to keep bothering me and stressing me out.
That doesn't sound right when it comes to the same app prompting. Have you checked your Settings > Privacy > Location Services settings, especially for those apps that seem to be doing this? Perhaps you have some sort of restrictions enabled?
