Missing checkbox

I’m having the same issue on my clients website. On Google Chrome the chekbox shows up, and even only clicking on the text works fine.. But in IE or Edge, the checkbox just doesn’t shows up, and a simple click on the sentence “check this box to confirm you are human.” doens’t work here either.

This is really frustrating the client, since his website has gone live a few days ago… I googled a lot and find some solutions for V2, but nor for V3… Can the author please help me with this ASAP? My client still believes that 90% of the internet users, uses IE or Edge, and not Chrome, Firefox, ..

So, now the client asked me to remove the whole checkbox thing.. I found a way to edit it in a Pro version, but since there hasn’t been released one yet, i’m hoping the author could help me (and all the others dealing with this issue) out ASAP..
