Can't disable double opt-in

[HundredViews]

Hi! 

I've set up the newsletter in my shop and installed ShopSync to sync my contacts with MailChimp.

Most of the things are working, but even though i disabled double opt-in, when you sign up for that newsletter it's still sending out an confirmation mail.
I also disabled double opt-in on my MailChamp list, but that thing worked great always anyway.

How do I fix that?

Is there nobody that encountered the same problem?

Really need help with that one, since my shop can't go live with that problem being there.

Don't want to be rude, but what kind of forum is that?
Are there even people reading this?

I really, really need help with this.

Alright, I got a solution set up where I have to add the mails manually. At least no double opt-in.
Would still love to get an answer how to set this up properly.
