Double Price updating (via the Service and M2E Pro Connector)

After the Product is added to Repricing Service, M2E Pro stops affecting its Price. It is made to prevent the double synchronizing of the Product Price.

If you want to update the Product Price via M2E Pro again, use 'Delete Items' action to remove it from Amazon Repricing Service or 'Disable' it to pause the dynamic repricing for a while.

The details can be found here.
