Not receiving push notifications in my iOS app if I send to "all users" from Firebase Composer

[Mobile Apps Studio]

I´m having problems to receive push notification from Firebase Notifications in my iOS app in the last hours. (Currently using 2.0.4 version for FirebaseMessaging).

I can receive push notifications if I send it from Firebase Composer (with a specific topic or FCM Token) but impossible to receive the notification if I use the default all users (segment) selecting the app.

This was working correctly the last week and I made no changes in my app (except update the CocoaPod dependencies).

Same behaviour if I try with the Firebase quickstart-ios example app from Github (connected with my Firebase Instance).

¿Any idea?

Thanks in advance.

I am having the same problem for sending push notification from the Composer UI for all User Segments. Been this way for over a week now with no resolution from their support yet.
