Could you please determine what exact term of the account can be considered as old? Since these accounts not older than 2 months, as you can see from the screenshots attached.
2 weeks. If someone signed up and didn't come back in that time they are not going to come back.
And I also want to remind you about these 4 mentioned referrals, who didn't show any activity from the beginning, as far as I remember, but still have been linked to my acc until the campaign launch. What about them?
They must have had some activity that didn't qualify for referral commission.
