• Update Software: If you are not on version 7.1 or later, update your software to the latest version to resolve this issue.

Understanding "Error 400: invalid_request"

This error generally indicates that the request sent to Google by Sparkbooth was invalid. It could be due to several reasons, such as an outdated application version using an old authentication method that Google no longer supports.

"Out-of-band (OOB) flow has been blocked" Error

The "Out-of-band (OOB) flow" is a legacy authentication method that is no longer considered secure by modern standards. Google has blocked this method to protect users. Sparkbooth has adapted to this change by updating its authentication process in versions 7.1 and above.

3. Reauthenticate with Google: Try authenticating with Google again. The new version uses an updated authentication method that should resolve the issue.

Troubleshooting Post-Update Authentication Errors

If you have updated to the latest version and still encounter errors:

• Check Internet Connection: Ensure you are connected to the internet and there are no firewall or network restrictions blocking the authentication process.
• Verify Credentials: Double-check that you are using the correct Google account credentials and that you have granted all necessary permissions for Sparkbooth to access your Gmail, Google Drive, or Google Photos.
