IOS >16 no location events with app closed

[LoghinAndrei]

Your Environment

• Plugin version: 4.17.1
• Platform: iOS
• OS version: 16.7.10
• Device manufacturer / model: Iphone 8
• React Native version (react-native -v): 0.74.1
• Plugin config

await BackgroundGeolocation.ready({
      // Geolocation Config

      // location for aggressive background-tracking to engage.
      // Note: iOS will not detect the exact moment the device moves out of the stationary-radius. In normal conditions, it will typically

        channelId: TRACKING_CHANNEL_ID,
        channelName: I18n.t('mining_title')
      }
    });

Expected Behavior

Receive background location events after the app is closed.

Actual Behavior

When the app is closed, the location icon disappears almost instantly and no other locations are sent until the application is reopened.

Steps to Reproduce

1. Start the background location service
2. Close app normally
3. Start moving

Context

We have noticed that ever since IOS 16 the number of locations we receive reduced drastically. We have tried different configurations to make it more aggressive and still cannot figure out a solution.
