Google recently updated their terms of service for reviews. You can read them here:
Read our full blog post explaining the change but for now we had to turn off Gboost and we HIGHLY RECOMMEND you do not use a Google link with our Push A Platform feature. We explain this more in our blog post but basically Google does not want you pushing happy customers to Google directly for a review. Unless you push the unhappy customers there too. Our Feedback and Review flow ways of getting feedback and reviews are compliant with Google. We now show your review links on the happy and unhappy feedback pages.
Please email support with any of your questions.
