Reproducible demo

export const registerForPushNotificationsAsync = async () => { try { if (Constants.isDevice) { const status = await getNotificationsPermissionStatus(); if (status !== Permissions.PermissionStatus.GRANTED) { return; } const token = await Notifications.getExpoPushTokenAsync(); return token.data; } } catch (err) {

Here we never go in the catch and we never reach the “return token.data” line

Ok, found the problem : We are using Intercom react native library, and setting it up we added this line :

But now the didRegisterForRemoteNotificationsWithDeviceToken is not returning anything, so the expo getDevicePushTokenAsync never resolves…

The solution : If you are using a third party library that asks you to implement something in didRegisterForRemoteNotificationsWithDeviceToken method, make sure to return to keep expo notifications working : return [super application:application didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];

I got the same issue than @thibaultfischer: Intercom react library seems to have an issue with notification token. The fix proposed by @thibaultfischer is working fine: In the file ios/MyApp/AppDelegate.m, I replaced:

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    [IntercomModule setDeviceToken:deviceToken];
}

By:

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    [IntercomModule setDeviceToken:deviceToken];
    return [super application:application didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
}

Then, I updated the getExpoPushTokenAsync() params to add the experienceId and applicationId:

import { applicationId } from 'expo-application';

[...]

  const { data: expoPushToken } = await Notifications.getExpoPushTokenAsync({
    experienceId: '@my_company/my-project',
    applicationId,
    development: 'dev' === Constants.manifest.extra.ENVIRONMENT,
  });
