Situation: I have a newsletter subscription site that client wants to bundle subscriptions for a cost savings to end user and so I created the list in listmailpro and configured the list to add new members to the other lists but this doesn't happen unless I export the list and manually re-import it removing dupes and all is well. Question: Am I missing something here? Why doesn't amember allow me to create a single subscription to multiple lists?
When aMember adds a customer to the list in the ListMail, it just adds a record to MySQL database. ListMail has no chance to know it happened, and add him to another list. It is clear why it happen, no bugs here, it just work this way. Regarding your problem resolution - contact us via helpdesk, and we will suggest something.
