I try incognito… and now the error is not anymore on HandL UTM Grabber. The issue is on Elementor. Now forms are coming with the right UTM’s fields. Thanks @haktansuren!
I just did that. Clear the cache, and try on a different browser, and sadly the error is still there. Let me know if you see an updated version from your side. Also, I share here what I have added to Nitropack settings. For me looks correct…unless you see something I have not added.
