After updating to the latest version of Microsoft Edge (version 93.0.961.38) today. I noticed that I unable to login to Apple Support Community Forum and Apple Developer Forum. The only way which I can do is to downgrade to the previous version of Microsoft Edge (92.0.902.84). That some how solve the problem.
These problems also have an issues with Google Chrome version 93. And that is confirmed.
