Just went to Cakewalk Command Center (about 10 a.m. eastern time on Friday 4/21) and found the April early release available (right click despite green indicator on Sonar then hover over rollback option to see full list, which is getting pretty long). I did not need to go to settings to run "Check."
I did not download/install right now due to competing priorities, but thought it might be useful to post that the availability is working as expected now (at least for me).
