We are enabled Secured Push on recently updated 5.4.1 server version and test that on 4.34 mobile version.
Users says that #4199 still an issue on 4.34. So, that problem not completely fixed by that PR.
Actually as for me - I have all push notification with full message text on iPhone during Secured Push test.

@ankar84 I'm not sure I've followed.
Is it working on Android?
Is it working on iOS only for you?
Is that it?
