For the last month or so, it seems like something changed with the Mailchimp API that makes exporting all campaigns way slower. Now, the extractions almost never succeed, instead timing out while trying to do a full table replication of campaigns. This should not be a large dataset, but something seems to have changed that requires the Mailchimp integration to be fixed. We work with six different organizations who use Mailchimp and all of them have started to see this happen.
