First issue:

Last night, restarted my mac. When I opened it again and open my Office apps, I am hitting the error "Sorry, we are having some temporary server issues.".

There is a button "Try again" which will either redirect you to the same page, means still the screenshot above or will redirect me to the next page:

Notice that the NEXT button does not do anything. It does not redirect me to any next page. I tried to click the "View Privacy Statement" link at the bottom left just to see if the page works at all but it's not doing anything. I am stuck in here!

I have tried to do some of the advices I see online like Force Quit the app, restart the mac (I did like 30 times) since last night and nothing happens! Please help!
