Worklight: two users Same device Push subscription -

i have scenario presented business team that: 1 person has device , subscribed push notification, later on wife use same device , subscribe push on account.

now in case:

1. will push go 2 times same device?
2. or, previous device subscription overridden

plus, app saves push notification messages on user's devices (as transaction history) , shouldn't problem!

to handle scenario, possible options?

i using worklight consumer 5.0.5

thanks

once subscribe different user on same device old subscription deleted. done security reasons, e.g. in case sell/loose/give device new user should not notifications of old one.
