Recently updated contact form 7 and I see googles recaptcha has moved from V2 to V3, so updated etc but now I see a small box to the bottom right hand corner with the ‘protected by recaptcha’ on a hover over..
I do believe that Google set certain citations about this when you sign up for reCaptcha. ie. you must inform users that this technology is being used. You may want to check that first, but not advising you do this but you can try this:
I wonder then if the box can be switched to the opposite side (so to the left instead of the right) because it interferes with the go back to top button right now.
