Why I haven`t received the nims for an invited friend
Check if the accrued nims are displayed in the "Events" section.
Try to use the to share your code with a friend.
It is also possible that a person you invited has already registeres in the app before. Registration of a particular phone number can be performed just once, and if an invite-code wasn`t entered right while creating an account, you can`t enter it afterwards.
