Thanks for your inputs. However, the platform support guide still doesn't provide any information on supporting Edge as a browser. Rather it says "Windows 10 ships with two browsers: "Edge" and IE11. Only IE11 is supported in Pega 7.2. (Edge will be supported in a future version.)"
May be we should be waiting for the updates as you have proposed.
May I request you to keep us posted on any updates happening in the Platform Support Guide in this regard?
