I have a when I submit datafeed to the google merchant. It runs well about 2 days, then all of the products come to the Inactive. Then I submit the datafeed manual again, then the data feed status change "Disappoved". After that, the status always "disapproved" although I submit lot of times.
And I recieve the email from google, They just said: Feed Level Messages Error: Disapproved - Error Your data feed has been disapproved because some or all of your items are not complying with our Program Policies.
