Kaustav Banerjee on "[Plugin: MailChimp Newsletter List Builder by SumoMe] Sumo Me List Builder / Mailchimp subscribers list not getting update"

I have been searching all through the forum and have done all required, but my MailChimp list is still not getting updated. My Sumo Me plugin has collected 5 emails already but they do not add up to my MailChimp list.

I have created a MailChimp list and uploaded 20 subscribers (previous ones) to it from a CSV file. After that, the next ones from Sumo Me are not getting appended to the list.

Please help fast!
