What is the Skate playtest survey from march 11th

Definitely very late to this but on the 4th I received an email (shown below) is the survey something linked within the email or was it something separate as I haven’t seen anything about it. Also if I haven’t received anything relating to the playtest (as I know many have been sent emails saying it releases 2pm tomorrow) does that mean I have not been accepted. I’m very new to play testing and have been very excited to play skate. At any point in time :D
