As per release 190822 which addresses PayPal’s Subscription Modification Button update…How does it now work when a free subscriber (Level 0) wants to upgrade to Level #1 (Paid).
In the past, you’d use modify=1 and level=1 in the PayPal button code.
I understand that PayPal now defaults/forces to use modify=0 but how does s2Member handle this or how should a custom PayPal button be coded. (I am using standard PayPal subscribe button code with the extra advanced variables).
Does s2Member still work when a free subscriber wants to upgrade to Level #1?
