Antonios review for Nabu for Google Shopping Feed

I have been used this app for 3 years, at the beginning I had no issue with them. But lately they import products with missing colors and missing size, even if I told them about this issue about 7-10 days ago, they never bothered to fix the issue. Now I do not know what happened in my merchant center from 120 clicks per day it god sudden drop to 19 click also with 60-70% drop in impressions. I had no issue with merchant. Update, they also have a bug issue with the draft products, if you have products at draft their app will be pushed to your merchant causing some issues and risk misireinterpretation.
