Help: Cannot call methods from expo-notifications and expo-firebase-analytics

SDK Version: 41 (41.0.0-beta.2)
Platforms: Android
Dependencies:
“expo-firebase-analytics”: “~4.0.1”,
“expo-firebase-core”: “~3.0.0”,
“expo-notifications”: “~0.11.3”

It seems I cannot use the native methods from those two packages (until now). I received error messages like blow:

based on that error, it looks like you’re not importing expo-notifications correctly.

you appear to have:

import Notifications from 'expo-notifications';

it should be:

import * as Notifications from 'expo-notifications';

see: Notifications - Expo Documentation

likely you have the same problem for expo-firebase-analytics

Thanks for helping me, it works!
I thought these two ways do the same thing.
