I was merrily bumbling along with the Power Up course when video 2.10 asked me to relaunch the browser. Since then when in incognito mode it asks me to sign in to MO365 to watch each subsequent video. However when I click sign in, it looks as if it works (pop ups are unblocked), but it just stays on the same page and asks me to sign in again! How can I overcome this so I can finish the module please?
