After updating to v9, we are running into some issues for IE11 users. Our solution contains a custom button on the command bar for the case entity. This button is no longer working with IE11 after the update. It is working as intended in Chrome, Firefox, and Edge.
We have a custom command with javascript connected to this button, but this javascript doesn't appear to be reached in IE11. I tested this by adding the debugger; keyword to the top of the command method... debugger does not hit the breakpoint. Not even when all other code in the method is commented out.
Has anyone ran into similar issues with IE11? Please let me know if you have!
