if product havent any review, ratingcount and ratingreview fields not set automatically. must be turn empty values.
We checked the issues, these messages are only warnings, and if we send empty rating values, we will get errors, not warnings. If we remove aggregateRating completely, we will get the "The aggregateRating field is recommended. Please provide a value if available." warning. Google just gives recommendations, it shouldn't have any negative effect.
also json addon dont work new phone formating system. phone area getting error
Please describe the issue in more details.
