Seems to be a major problem on one of my Ipads. Keep continually getting the smartmoney ad plus the angry birds redirect. The problem is confined to FT as using the same Ipad on al the other websites I use does not bring up any ads.
Have reset the Ipad and turned all security settings up to max.
In essence, these disruptive ads make FT use of FT very difficult and give cause for concern as they could lead to more problems than just disruptive ads.
