Yes it is the latest version of the plugin (Version 1.35.0). Also, it may be helpful for you to know the checkout is an Elementor page with the Elementor Checkout Widget. I have a feeling that might be related to the issue. The rest of the Elementor forms are working nicely with the Turnstile Integration though.
I am seeing the same issue on Elementor forms.
It looks like it works without any extra formula. I guess don’t need any assistance with this.
Thanks!
