The product ID's no longer match, therefore all the data collected through years of advertising on Google is lost. This is a real problem for me. I would rather use a buggy version of the plugin that gives me the right ID as it's way too much work to try and download the xml, , convert it to csv, loop through and filter out the unnecessary characters and then create a new xml file which I then have to manually upload. This makes no sense when using a paid pluggin.
Alternatively, please incorporate a way to refine how the product ID is created. Right now there is no access to this. If the ID is <1234_123123_12_242354254> then please allow me to make it <1234>.
