The Invite-A-Friend link that Stepler has generated can be very sensitive since it has several checkpoints in the invite process to prevent cheating, these checks can however fail even on a legitimate referral, what you can try to do is the following:
- Make sure they are not a current or former Stepler user
- Make sure that your friend goes through the referral process in one go as to not interrupt the process
- Ask you friend to click the link you sent again
If the steps above do not work you can send us an email at email@example.com and we can transfer your points manually.
