Hi Szabi,
Thank you, we were running v1.1.2 so update worked.
We were also a little confused by the language.
We were using the “organizer_id” instead of the “organization_id”, so changing this helped.
I might suggest updating the plugin menu item to “Search by Organization” instead of “Search by Organizer”
But thank you so much for the quick reply, very happy with the results!
