It looks like Microsoft has changed the way they update Microsoft Edge. I have tried 12.6.1 HF6 and downloaded the master files to see if I could upgrade Edge on Windows 10 21H2 (OS Build 19077.2604). I noticed in both versions, that the new Edge is not downloaded and it looks like Microsoft has changed the naming convention on the files. When I attempt to download from the following sites, the name do not match what is in the code: https://www.microsoft.com/en-us/edge/business/download?form=MA13FJ and https://www.microsoft.com/en-us/edge/download?form=MA13FJ.
