in the UK I had the same experience. Jardines in Kent said they we accessing the portal as we were speaking and amended my order (minor change). They saved it then emailed me a pdf version.I spoke to my agent the other day (texted his mobile), and he said that he could call me this coming week to discuss any changes that I wanted, as he was able to make those changes on his portal now.
They also mentioned that my predicted build date showed Feb 23. This, as is now, was showing blank when I accessed the webpage and logged in.
