Leanplum Firebase Services won't load

[fede1608]

I'm updating the leanplum sdk to 4.0.0 and moving to FCM but I'm getting this error messages when my app starts:

04-20 09:28:27.711 15184-15233/com.xxx E/[ERROR][Leanplum]: [com.leanplum.internal.LeanplumManifestHelper::checkComponent::252]: Push notifications requires you to add the service com.leanplum.LeanplumPushFirebaseMessagingService to your AndroidManifest.xml file.Add this code within the section:

I've added this to my gradle file

    implementation 'com.leanplum:leanplum-fcm:+'
    implementation 'com.leanplum:leanplum-location:+'

And I've tried manually adding the services and also letting the manifests merge but it always throws the same error, I've checked the debug manifest that's generated, and both services actually appear there.

Specifications

• Version: Leanplum sdk 4.0.0
• Platform: Android 8.1.0
• Subsystem: Google pixel 2 XL

I went back to Leanplum sdk 3.0.2 for now.
