I seem to have been left out although I enrolled 2 months ago and submitted the 2nd form (the one where you claim payouts) ~9 days ago.
Should I just send a PM?
You submitted the claim form on 9 days ago? You're meant to do it on the 17th. Yes, I'd send him a PM.
I think it doesn´t strictly point to which date I should submit it on, which is why I did it ~9 days ago.
I also submitted it then as I enrolled on ~19th June.
While the offer stated that payment was based on posts for every 30 day period, it did not specify any deadline as to when to submit the form.
