have been trying to log in to my Microsoft account on my new laptop. I have previously used the 2-factor identification method on my old laptop, however, it doesn't seem to be working for my new laptop. When it says it has sent a notification to approve on the authenticator mobile app, nothing is coming up to approve on my mobile so i am making no progress. I also cannot find a code to enter on my laptop from the app. There is no QR code to scan on my laptop using the authenticator app. I don't know what to do and it is extremely frustrating because I cannot access anything, emails etc. Would be very grateful for some help. Thanks.
