I think it's also important to have an additional "referral code" to be manually used when referrals sign up. This is useful for users sign up via mobile app... during registration, a "referral code" field can be optional added....
this is a good suggestion. Also getting a referral code option to register as alternative for referral link will work fine. think this can be look into. I have upgraded my UNA to 13-A3 and both the referral system and points module are no longer working.
