Unable to run K2 workspace in microsoft edge.
K2 blackpearl version is 4.6.10.
Go to Solution.
Microsoft Edge is not supported in K2 blackpearl - K2 Product Compatibility, Integration and Support (nintex.com)
Maybe you can try IE tab plugin for Chrome, it look like there is an extension for this in Edge browser. Like AMolyneux said, Microsoft Edge is not supported for Blackpearl, your mileage may vary on this one.
