Nosto

OMG !!! i am really pissed off with this app ! This is the first bad experience i had with an app on shopify
First it took a while to get the app : a lot of problems and back and forth
the support told me that the app is working but finally not

After a loooooooooong wait, when i finally get the app, the trial time was over, even when i have never use the app,
And the worst, the app caused some troubles on my website and Nosto support don't answer my email.

Nosto support, if you read me, fix the problem you did on my website !

Nijala website

Completely wrecked my FB ad account. Don't walk... RUN from Nosto.

NO WAY! This thing only created massive errors and did not work at all. Talked to customer support with no help. Not worth our time.

Based on what I have read its great for FB marketing. But its not clear until after I installed it that its only using Retargeting Techniques and nothing else.
Now deinstalled it.
