> Update as of 04/23/2021: The plan to disable TLS 1.0/1.1 by default is being updated for Internet Explorer and EdgeHTML (the rendering engine for the WebView control). TLS 1.0 and TLS 1.1 will not be disabled by default for both until early 2022. Organizations that wish to disable TLS 1.0 and TLS 1.1 before that time may do so using Group Policy. Microsoft Edge Legacy is no longer in scope for this plan as the support ended on March 9, 2021.
> There are no changes to the plan for the new Microsoft Edge (based on Chromium). TLS 1.0/1.1 were disabled by default starting in Microsoft Edge version 84, and the SSLVersionMin policy that permitted enabling the legacy protocol versions will be removed in version 91.
I'm guessing postponed due to not wanting to interrupt business during the pandemic where they may be short-staffed or other preoccupied.
