I appreciate that this is a free extension and therefore probably not very high priority, but it would be nice to get a reply given that this forum is the only access to support. There is also another topic in this section (about GDPR) awaiting a response. I like this extension and the fact that it integrates into Matukio (which I have a current licence for) and really don't want to be forced to look for an alternative.

Hey Christian,

Without access to your backend and most probably ftp for debuggin I can't tell you why the extension is not working.

I can tell you that I just tested it with our lists and the synchronization is working just fine.#

Daniel

Site and FTP details added.

What are you doing exactly? I clicked on list synchronization, selected one of your list - hit synchronize and the list was synchroniezd?
