Used the following example to test:

import React, { useState } from 'react';
import Mapbox, { Camera, MapView, UserTrackingMode } from '@rnmapbox/maps';
import { Button } from 'react-native';

const App = () => {
  const [followUserMode, setFollowUserMode] = useState<UserTrackingMode | null>(
    UserTrackingMode.Follow,
  );
  const [followUserLocation, setFollowUserLocation] = useState<boolean>(true);

  return (
    <>
      {Object.values(UserTrackingMode).map((mode: any) => (
        <Button
          key={mode}
          title={`${mode} ${mode === followUserMode ? '(active)' : ''}`}
          onPress={() => {
            console.log('setMode', mode);
            setFollowUserMode(mode);
            setFollowUserLocation(mode != null);
          }}
        />
      ))}
      <MapView style={{ flex: 1 }}>
        <Mapbox.UserLocation visible showsUserHeadingIndicator />

        <Camera
          followUserLocation={followUserLocation}
          followZoomLevel={20}
          followUserMode={followUserMode}
          onUserTrackingModeChange={(event: any) => {
            console.log(` => ${JSON.stringify(event.nativeEvent.payload)}`);
            console.log(
              `onUserTrackingModeChange(${event.nativeEvent.payload.followUserMode})`,
            );

            setFollowUserMode(event.nativeEvent.payload.followUserMode || null);
            console.log(
              `setFollowUserLocation(${
                event.nativeEvent.payload.followUserMode != null
              })`,
            );
            setFollowUserLocation(
              event.nativeEvent.payload.followUserMode != null,
            );
          }}
        />
      </MapView>
    </>
  );
};
