Hey, that is because as i mentioned in my previous email, i have rolled back to the previous version of PPOM 16.3 since 16.4, 16.5, 16.6 and 16.7 all have the issue i mentioned and my store will lose sales if i enable that version to test. Are you able to create a variable subscription on your demo installation with attributes and see if you have the same issue as me during cart and checkout?
Thank You!
