Doesn't Autofill appear at the top of your keyboard? I haven't used my iPad in ages, but that's where I find it on my iPhone. Just touch it to populate the fields.
Just a thought, Sam. Are you using Safari in private browsing mode? If so, it won't allow autofill to input the data.
So. not in private mode then.You would have a black background if you were in private mode.
By the way - there is no such icon as 2 squares at the bottom of the Safari page. Are we at cross purposes here? Are you referring to iPad and not iPad Pro?So. not in private mode then.
