How to check if Finesse is running in IE11 mode

If “Display Intranet Sites in Compatability View” is checked and Enterprise Mode is NOT configured for the Finesse Site, then it will run in IE8 mode.
Press F12 and see if running in IE11 or IE8 mode at the Finesse Login Page - as per below screen shot
If you see “Edge” you are running in IE11 mode. If you see “8” - its not supported (for Cisco UCCX / UCCE)!
