                negativeAction: "Cancel",
            }
        })

Expected Behavior

App does not hang and location tracking is consistent with the Philosophy of Operation

Actual Behavior

Getting "App Hanging" exceptions in Sentry:

BeSafeWorkAlone     0x100f366dc  -[TSLocationManager ready]
BeSafeWorkAlone     0x100664408  __49-[RNBackgroundGeolocation ready:success:failure:]_block_invoke (RNBackgroundGeolocation.m:187)
...
BeSafeWorkAlone     0x100f3f25c  -[TSLocationManager locationManager:didFailWithError:]

Steps to Reproduce

1. Start location tracking

What is an "App Hanging exception"?

[mcottingham]

I don't get a whole lot more context than this. Looks like perhaps TSLocationManager is causing the UI to hang for over 2 seconds?

[christocracy]

Let me know how to reproduce.

[mcottingham]

I'll just close the ticket. I thought maybe you would have seen this before.

Never heard of it.

That method does little more than fire a LocationError event, which iterates over an NSArray of callback-functions and executing them.
