Hello,
There are not real standards for push notification services, and some does not support this playload lenght. If affects the push behavior on some browsers as Firefox for Android.
Reducing the playload lenght and automatic padding can be a solution :

$webPush = new WebPush();
$webPush->setAutomaticPadding(2048);
