Why can't I sign in?

There are a few reasons that you might be getting stuck during sign in. Rather than list them all, the best thing to do is try signing in with your Google or Microsoft account. Remember to use the same email address that you've used previously.If that doesn't work, try signing in using an incognito window. If you're able to sign in that way, you'll want to clear your cache and cookies on your browser to correct the issue.
