Hi. I'm using 123form builder app in WIX for a customer who has built the site but says the contact form doesn't load on their iPhone (3g). We are using this app to enable google Captcha. Also very slow to load on several other devices. I've tried adding the form directly in Wix. Also tried embedding js code and iframe. Both render equally slow/not at all. Any ideas? I should say - it works totally fine on my devices. They tried clearing cache and the usual.
