Hello bizzy,
We are not receiving reports that would indicate that this is a widespread issue, but you should be able to mark an email from as as 'Not Spam' when it hits your Spam box on Gmail to move it to your inbox. While you may need to do this more than once before Gmail stops sending them to your Spam box, it should set your account to stop treating the messages as Spam.
If you have any further questions, please feel free to file a support case from under the Help tab of your account.
