Microsoft Edge still doesn't work well with some legacy websites.  Officially, it is not supported by ProSeries.

Given the vulnerabilities and Microsoft's own statement about IE, it is difficult to understand why anyone would still want to use it (https://techcommunity.microsoft.com/t5/windows-it-pro-blog/the-perils-of-using-internet-explorer-as-...).

If I were you, I'd give Edge a try and rollback to IE 11 in case it doesn't function correctly.
