I received an email on 21st March as follows
Your SharePoint Online
environment will soon receive a planned service update beginning within the next 24-48
hours and will be completed within ten days.
I have heard nothing since and the site collection upgrade feature says it is currently disabled.
The look of the site is still the "orange style" not the new styel - which i have seen working on another business i run.
How do I know when this update will or even has occured - as i am holding on certain decsions re design etc until such time as we have the new capabilities.
