Troubleshooting: Social Login Problems
Social login problems are usually about the provider session, not the calculator. Start by checking which Google, Microsoft, or LinkedIn account is actually being used.
Likely cause
If social sign-in fails, the provider may not have completed the handoff back to GridGap, the provider account may not expose the email address the app needs, or the flow may be returning to a page that expects a different account context.
Common checks
Check for popup or redirect blocking, signing in with the wrong Google, Microsoft, or LinkedIn account, starting from an invitation flow and then using a different email address, or retrying after the social session has expired.
What to check
Retry the sign-in using the exact provider account that should own the GridGap account or invitation. If the problem happens from a workspace invitation page, make sure the provider account uses the invited email address. If the provider flow returns you to login with an error, try a full sign-out from the provider, then start the sign-in again from GridGap rather than from a saved provider session.
If social sign-in still fails but you know the account email, try the standard email-and-password route instead. If you never set a password because the account began as social-only, use the contact form or, if you can still access another part of the app, open a support ticket.
