I have implement this extension and its working good except one thing. Products expiration date field for Google shopping is not updated while synchronizing.
I have Google a lot and found out that we need to delete and re upload all the product again which are expired, which i thing is not a good solution( Since Google takes a lot of time to review any new product)
On debugging i found that
this is always sent to Google while adding or synchronizing product, but while synchronizing the value of this field is not updated and hence product expires in 30 days on Google merchant.
Is this a know issue ?
Has any faced this issue?If yes, then how it can be solved.
