Microsoft Edge

Is anyone using Microsoft Edge?  Are you seeing any issues?  I personally use Chrome, however, some of our team in APAC recently converted to Windows 10 and are now using Edge.  From time to time, even though Smartsheet is accessible, they see weird things, such as yellow highlights of cells that noone else is seeing, yet if they refresh, it may look normal again.  Has anyone else seen these mystery lights or anything else weird.
