Clicking on one notifications clears all - APNS

[pawanshakya]

When user receive 2 or more different notification( different parameter in payload under data) while iOS app (using APNS) is in not running state. Clicking on one of them shouldn't remove all remaining ones as well in notification centre.
As in android, setting "tag" in payload allows user to click separately on each different notification though.

In iOS, do we need to set some specific condition or form payload differently to avoid this? I have tried with setting "thread-id" in payload , didn't worked though.

Can you please help in this regard.
