Help with background location task

[rlplayer]

Please provide the following:

1. SDK Version: v0.35.0
2. Platforms(Android/iOS/web/all): IOS

Hi I am currently seeing two minor problems for background location tasks.

1, When the app first ask me for permission, even if I selected while in use(there is no option at first to say Always), the Permissions.askAsync(Permissions.LOCATION); would still say the scope was always. This can be annoying because I do not want the background task to run with the blue indicator later on.

2, After running in the background for a while, IOS will ask me if I want to change the permission to Always, my app would immediately throw a promise rejection during this part

[Unhandled promise rejection: Error: Cannot obtain current location: Error Domain=kCLErrorDomain Code=0 "(null)"]
- node_modules/react-native/Libraries/BatchedBridge/NativeModules.js:155:41 in createErrorFromErrorData
- node_modules/react-native/Libraries/BatchedBridge/NativeModules.js:104:55 in <unknown>
- ... 5 more stack frames from framework internals

I was wondering is there any way for me to catch this error?

Thanks in advance if anyone can help me with these problems, really appreciate it.
