Referral not tracking

Can anyone tell me how long it takes for a referral to show on your account?
My friend joined through my FB link on 18/03 but I’ve not seen any updates since then. Thanks!

@Hippichic, if they signed up via your link on the 18th, you should already see it on your referral page as a switch in progress.

@Hippichic If they signed up on the 18th then switching takes 21 days. The referral credit is added on the evening of the day they switch.
