Cannot Author Data Factory on Edge

I know this is not a graph issue but thought id make an issue as you might be able to pass it across internally

I have adapted the .md document to notify that https://adf.azure.com/ doesn't work on Microsoft Edge Version 81.0.416.68 (Official build) (64-bit). 

This is the document in question above:
