Hi everyone !We are looking for a way to promote our app through a sponsorship program where a client "A" can give his personnal sponsorship code to a friend "B".If the friend "B" suscribes then client "A" will get a free month (for example) or another reward for sponsoring someone.I think UBER is using something like this.Do you think it is possible to implement such thing with Apple ?If not, do you think there is another way to do it ?Thanks a lot for you answers !Regards
