On January 15, 2020 Microsoft released their new Edge desktop browser (version 79). This marked their first release of an Edge web browser based on the Chrome browser engine, Chromium.
In August 2020, Microsoft announced that support for the Microsoft Edge Legacy desktop browser would end on March 9, 2021. After this date, Microsoft Edge Legacy would no longer receive security updates.
This change primarily affects Windows 10 users as this was the default browser installed with Windows 10, however it is possible that some people have installed the legacy version of Edge on other versions of Microsoft's windows operating system.
While people have been able to upgrade Edge to the new chromium version since its release in January 2020, Microsoft will force the update in their Windows 10 cumulative monthly security update on April 13, 2021.
At this juncture, nothing has fundamentally changed in MHPOD that would preclude Microsoft Edge Legacy from working, however as the manufacturer has ceased support for the browser so has MHPOD. We will no longer test new releases against Edge Legacy so over time as new capabilities are added or isues are addressed it's possible that Edge Legacy will delivery a sub-standard experience.
We highly recommend that you update your browser to the latest version of Edge or use a different browser for MHPOD.
