Hi! I have the trial period set at a higher amount, since it seems to be the way to charge a set up fee or to make the first month have a different price than the remainder.
Today I cancelled one subscription per user’s request, the IPN was sent to s2Member but it returned [0] => Ignoring this Webhook/IPN. The event does NOT require any action on the part of s2Member. instead of setting the EOT as it should.
Below a copy of the log entry for the event. I wonder if the same issue will happen when a subscription is cancelled after those 30 days for someone else. I’ll keep you all posted as usual
