This has blocked an important user scenario we are trying to support. The user can't sign-in as a result.
I'm embedding the oauth sign-in page below in an iframe in my integration. When the user clicks on "Sign in with Google" it opens the google sign-in in a new page instead of navigating to google sign-in. This is problematic because Mac OS Excel opens the new page on a totally new browser process that doesn't share cookie with the embedded browser inside Excel, so after google sign-in there is no way the embedded browser inside Excel to get the cookie token. As a result, it is impossible to sign-in via Google. I looked at the code of hubspot sign-in page and found that opening google sign-in in a new page is on purpose when it is in an iframe. When using the sign-in page directly in the browser without iframe, it navigates to Google sign-in instead of opening in a new page. Why is that? Is there a way to make hubspot sign-in page loaded inside an iframe to also navigate to Google sign-in? Thanks!
