I am building a website. I noticed that when entering text in the contact form from mobile phones there is this odd delay, anywhere from 1-10 seconds before the letters or words I typed appears. On my computer and laptop it is fine, no lag. On my iphones 10 and 7, I tried safari, chrome, and edge...they all do it.
It's a fairly straight forward contact form, uses php on the back end. The server resources are good. Internet connection is fast, just wondering what would possibly cause this lag only on mobile.
Not really sure where to start. Should I be looking for in CSS config?
