Hello, i have exactly the same problem but with my zap for Systeme.io to AWeber.
It’s for my newsletter registration.
It correclty works in test mode, but when i do a “fake” registration on my optin page on SIO, nothing appear in zap history and nothing appear in new subscriber in AWeber…
I tried with trigger “new optin” and “new tag is added” but it’s still the same…
