        zoomTapEnabled={true}
        showsUserLocation={true}
        userLocationPriority={'high'}
        scrollEnabled={true}
        showsScale={true}
        showsCompass={true}
        userInterfaceStyle={modeType}
        onClusterPress={(cluster, markers) => {
        }}
        showsTraffic={true}
        showsIndoors={true}
        onPress={handleMapPress}
        followsUserLocation={false}
        ref={mapViewRef}
        tracksViewChanges={true}
        clusteringEnabled={props?.cluster == false ? false : true}
        // for cluster view
        preserveClusterPressBehavior={true}
        loadingEnabled={true}
        mapType={mapType}
        onMapReady={(e)=>{
        }}
        initialRegion={initialLocation}
        onPanDrag={(e)=>{
         debouncedOnRegionChange(e)
        }}

        style={styles.container}>

 <Marker
                coordinate={{
                  latitude: userLocationHeading.latitude,
                  longitude: userLocationHeading.longitude,
                }}
                anchor={{ x: 0.5, y: 0.5 }}
                rotation={userLocationHeading.heading}
              >
                <HeadingMarker heading={userLocationHeading.heading} />

Hi @Hamza-Akva thanks for reporting this. I was trying to reproduce it on iPhone 12 with iOS 15.5 and iPhone 11 with iOS 17.2 and it works perfectly fine. Is it happening only on certain mapType? Also can you try to reproduce it without onPanDrag prop? Because maybe something in this function is causing this problem and I don't know whats your function body is. And if you can please remove all props non necessary to reproduce this bug, it will be easier for us to reproduce, and fix it.

Hi @chanphiromsok can you open your own issue with full description and source code? Or if it's exactly the same case please provide your code here

Hi I have been testing on new project is work fine it maybe conflict with some deps install I will create reproduce repo sample for you because it's a private project

@mateki0 Hi I figure out the issue is I used MapView in the Context and Wrap my whole Navigation inside it after removed it work fined now not freeze

  <BackgroundGeolocationContext.Provider value={{ listen }}>
      {children}
      <MapView
        liteMode
        style={{ display: 'none' }}
        showsUserLocation={appstate === 'active'}
        userLocationUpdateInterval={500}
        showsBuildings={false}
        showsCompass={false}
        showsScale={false}
        showsPointsOfInterest={false}
        onUserLocationChange={onUserLocationChange}
      /> 
    </BackgroundGeolocationContext.Provider>

[chanphiromsok]

now I remove liteMode it work fine I can zoom map as normal

[mateki0]

@chanphiromsok does it work fine with liteMode and without your context? If so can you put here the code from this context?

sorry I did not test that case but without context map view using liteMode it work fine on other screens

[mateki0]

So do you need any help from our side? Because I'm a bit lost here now

no I didn't have the problem like you please share your environment

[chanphiromsok]

please try create with fresh project and test it

I'm running into the same problem with my Expo project, running it in Expo Go on native Apple Maps. Zooming in beyond maxZoomLevel is fine, but zooming out beyond minZoomLevel causes the map to return to that level, realign north, and freeze, rejecting all inputs until I go back a screen and relaunch it.

[m-peeler]

I've been able to get the bug to replicate all the way down to a minimal case of

import { StyleSheet } from "react-native";
import MapView from "react-native-maps";

export default function MyMapView(props) {
    return (
                <MapView 
                    style={{...StyleSheet.absoluteFillObject}}
                    maxZoomLevel={18}
                    minZoomLevel={10}>
                </MapView>
    )
}

running on an iPhone 15, which makes me guess it's either an inherent bug, or something wrong with react-native-maps' interactions with Expo/Expo Go?

@Hamza-Akva @m-peeler @chanphiromsok we've introduced cameraZoomRange for iOS recently to solve this issue natively, previously a custom code was used and it was buggy in some corner cases, including this one.
