Your Ad is preventing people entering the form

Your ad is preventing people from entering the form, this seems to be mainly on Samsung devices, but have had one complaint from an Iphone as well. 

Hi,

I can see that your form is embedded on your website may I ask if you have tried re-embedding your form using the iFrame embed method? If not, kindly try to re-embed your form using this method: Getting-the-Form-iFrame-Code

Then let us know if the issue still persists.
