I used the Acymailing extension.
When a new member join, he is automatically assign to a mail list in Acymailing (List2018).
When a renew is membership, I would like him to be assign a new list (List2019).
Current implementation, seems to only working when member is new and when member does not renew his membership on time.
Currently, we don't have a way to handle it. We just allow assigning users to the mailing lists when they have active subscription of that plan, it works in the same way for both new subscription, subscription renewal and subscription upgrade. There is no way to assign them to a different mailing lists on renewal
