As we kick off this effort, we need your help making sure we catch the most important issues and getting the word out! If you are encountering compatibility issues in the areas listed above, please continue to file bugs in the appropriate tool (either via the “Send Feedback” tool in Microsoft Edge, or directly in the appropriate project: Chromium, Webkit, or Gecko).
You can follow the project’s progress on the Compat 2021 Dashboard on web-platform-tests, subscribe to the public mailing list for updates, or follow @MSEdgeDev on Twitter for the latest updates from our team.
We’re excited to participate in this initiative to make the web an even better place to build great experiences that work across browsers!
