-Topic persistency will persistently push the notification until it succeeds.
+Topic persistency will repeatedly push notifications until they succeed.

 The default behavior is to push indefinitely and as frequently as possible.
 With these settings you can control how long and how often to retry an

-by providing maximum time of retention or maximum amount of retries.
-Frequency of persistent push retries can be controlled with the sleep duration

+All of these options default to the value `0`, which means that persistent
