Roll20 officially support only the Firefox and Chrome browsers, so issues with any other browsers(such as Edge) won't be directly addressed by them, and only fixed by lucky coincidence, in case some of their updates targetting Firefox/Chrome happens to have a wider impact. Based on the link David gave, it's probably a problem impacting chromium-browsers in general, so if you're lucky, things will work again on Edge when the fix for Chrome is done, but that's not guaranteed.
