Simprosys Google Shopping Feed

'This app created a lot of problems. Even after unnistalling it !'
I had a lot of problems after unnistalling this app, most of them because of disconected accounts between shopify, GAds, Merchant center and GA4 , so I gave them a bad review.
I've read in the last month a lot of good articles published by them, all of them very usefull. So I decided to give them 'trust' and I changed my previous review. I will give another try to this app on the next days to see if I was wrong.
