Try Microsoft Edge
A fast and secure browser that's designed for Windows 10
The buttons to expand and collapse an activity / email in Dynamics online, are no longer functioning. It does show the email for a split second, though it doesn't really expand. The only option left is to open the email in a second page by using the button.

Thanks, just have to wait for the update...
