Issue summary: On March 24, 2021 around 1:08 p.m. to 6:41 p.m. PDT on March 25, 2021, some users could've encountered "There's been a glitch" when trying to open workspaces with single sign-on (SSO) enabled. This error page appeared when using the email verification flow to sign in, where users are directed to their accounts after receiving confirmation emails. Affected users could still access their accounts by entering the workspace URLs, such as in a browser address bar, instead of using email verification. We discovered that a change we made caused this trouble, so we deployed a fix to resolve this for affected users.
