I would FIRE your CIO!!! Over the past couple of years, your Finance tracker has been a miserable example of very poor Change Management.
I would fire your CIO!!! The Finance pages are not accurate, lose data and have to re-load several times and even then are often wrong. You obviously changed something and it's broken. This is not the first time this has happened. This is a prime example of very poor Change Management. I don't feel like re-entering my portfolio data, but if I have to, it will be with Google.
