Microsoft Defender SmartScreen reporting US OAuth URL as unsafe

We have had reports of Microsoft Defender SmartScreen within Microsoft's Edge browser flagging some OAuth flows as being from an unsafe site. We obviously believe this to be a false-negative and have reported this to Microsoft. If users refresh the page Edge will allow users to continue without any warning. Based on this workaround being simple and indicative of the domain as a whole not being deemed untrustworthy, we are investigating if there is anything we can do to avoid this false-negative from our side.
