I implemented the Facebook App Invites feature into my app. Sending and receiving works fine in my app, but the Facebook user that received the invite on his Android app doesn't receive neither push notification or general notification as specified here. It only shows up in the App Invites section. Does anyone know what can I do in order to show a Facebook notification?
Facebook SDK 4.20
Invite sending
private void initFbInvite(final CallbackManager callbackManager, final View inviteButton){
Map<AppLinksManager.QueriesKeys, String> queries = new HashMap<>();
queries.put(AppLinksManager.QueriesKeys.SENDER, UserManager.getInstance().getUser().getId());
final Uri appLink = AppLinksManager.generateAppLink(AppLinksManager.Endpoint.FB_INVITE, queries);
StorageReference previewImageUrlRef = mController.getStorageReference().child("applink-images/fb-invite.png");
previewImageUrlRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
@Override
public void onSuccess(Uri uri) {
final AppInviteContent inviteContent = new AppInviteContent.Builder()
.setApplinkUrl(appLink.toString())
.setPreviewImageUrl(uri.toString())
.build();
final AppInviteDialog appInviteDialog = new AppInviteDialog(ExploreFragment.this);
appInviteDialog.registerCallback(callbackManager, new FacebookCallback<AppInviteDialog.Result>() {
@Override
public void onSuccess(AppInviteDialog.Result result) {
Log.d(TAG, "FB invitation send successfully");
}
@Override
public void onCancel() {
Log.e(TAG, "FB invitation cancelled");
}
@Override
public void onError(FacebookException error) {
Log.e(TAG, "FB invitation error");
}
});
inviteButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
appInviteDialog.show(inviteContent);
}
});
}
});
}
Custom App Link url used for this AppInviteContent
https://stellarscepter.com/clecs/fb-invite?sender=PsF6qaJPLKVnOjxr2Ufzs5cSVTZ2
index.html (stored in clecs/fb-invite folder on the server) for App Link metadata

EDIT 1:
I tried with either test and real Facebook user, that has already received an invite and not received any one. I also tried with users that have autorized and not autorized via Facebook. In every combination no Facebook notification shown.
Found out that is a Facebook SDK bug reported here.
