I have been struggling for days to fix a problem I am having with membership upgrades and S2 Member. I need to create a payment form that allows a user to upgrade their current members account to a higher level membership without affecting their current EOT time. I have read through the forums and tried several strategies but I can't seem to figure it out. No matter how hard I try when they upgrade their EOT time get's changed.
Goal is to upgrade their account to a higher level membership and keep their current EOT time.
I have tried the strategies in this older article but they don't work: https://www.s2member.com/forums/topic/modification-upgrade-of-level-on-s2member/index.html
