That would explain why I answered the wrong question.
I'll answer this one here as well because it helps reduce the number of questions I get if everyone can read the answers.
We delete old accounts that have never had any activity at all. So the reduction in the total number of referrals you have is just the removal of the ones that signed up for an account never used it at never came back.
Thanks for your prompt reply.
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.
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?
Thanks.
