Reproduction steps:
1. Open the attached "Archive" project.
2. Build and run the "Scene" for iOS.
3. Click the "GetLocation" button on a device.
4. Check the log in the Xcode.

Actual result:
STATUS = Initializing; Wait = 20
…
STATUS = Initializing; Wait = 1
FAILURE

Expected result:
SUCCESS

Regression introduced in:
5.4.1

Original note:
The user states that LocationServiceStatus returns true on the second call, and false on the first one. I've noticed that if two requests are active at the same time (if you press the button again before the first request times out) it seems to succeed.

To resolve the issue:
Set a value in "Player settings > Other settings > Location Usage Description".
