Hello It's not possible to approve two digit code via ISP with IPV6 (Phone connected to Wi-Fi). Each time i had to do it, i switch off from Wi-Fi to have IPV4. Thanks.

    I have a similar issue. Microsoft Authenticator and the Phone Link application on my PC cannot communicate with my phone when I am connected to my WiFi network. The only way to use these apps is to turn off WiFi and use my provider's 4G/5G connection.

    My phone has both IPv4 and IPv6 addresses so it does not appear to be an issue with IPv6 specifically, however, this problem first occurred after I got a new WiFi6 router.

    Is Microsoft aware of these issues with their apps?
