AM365 and Google Sheets Add-in SSO login redirecting to Anaplan Home
This item has been identified as an outstanding known issue. A workaround is provided until the issue is officially fixed.
If you have a live session on Anaplan on another tab, when attempting to authenticate via SSO, you will be navigated to Anaplan Home on the popup window instead of it redirecting and authenticating you on the Google Sheets Add-in or AM365 add in.
This issue is avoided by not having an Anaplan session cookie present. i.e if you sign into the Google Sheets Add-in/AM365 first before Anaplan, you will not encounter this issue.
Alternatively you can clear your cookies to wipe said cookie.
Another workaround would be to use a separate user profile on the browser or use incognito window for Google sheets/AM365 only.
