[require:location] only works sometimes

Not sure if this belongs here or in Design & Bravo Tags.... I'm making a social media app centered around posting and signing up for events. The home page filters all posts by whether or not they fall within a 50 mile radius of the user/device location. The only issue I have is that, after signing in when users first load into the home page, the variables for device latitude and longitude send to the API as "undefined". I've tried setting location services to "Always On" so that the app always see the device location, but it didn't help. This usually only happens when a user signs in, and bravo navigates to the home page on success. When reopening the app, being already logged in, it usually loads up just fine and the variables send with actual values for the latitude and longitude. It mainly just happens when navigating to the home page on login success. Any ideas on how to fix this? I'm already talking with bravo support to get to a solution, but I thought I was ask the community as well.
