As of early 2020, The Microsoft Edge browser is based on Chromium, and will be the only version of Edge that will be supported with Remotehour moving forward. Chromium is the same open source platform that other popular browsers like Chrome, Opera, Vivaldi, and others are based on.
Discontinuing support for older versions of Edge will help us to focus on improving Remotehour's reliability, quality, and feature set instead of supporting another browser family! Chromium Edge is supported on many different devices and operating systems as old as Windows 7, so update to the new experience here, https://www.microsoft.com/en-us/edge/, if Edge is your browser of choice.
