Same thing happening here. I specified V2 in Google Admin console, copied the V2 api keys, set the pluggin to use V2 recaptcha and it’s still trying to get https://www.google.com/recaptcha/api.js?render=6LfECUkUAAAAADuxo6gx-9V0xatKPvazklTRHvDQ&ver=3.0
The only solution is to disable recaptcha or move to another plugin ??
