Hi Maya,
Hope you are doing great today!
I understand your concern and I am sorry for the inconvenience caused to you by this situation.
I’m not seeing the images you’ve shared, please use any file sharing site like WeTransfer or Imgbb
Anyway as first attempt lets try to fix it by starting the process from scratch.
Not sure if all the steps below will apply, it depends on how the onboarding process ended.
1. Go to Settings tab on “Marketing > Pinterest”
2. Disable “Enable product sync”
3. Enable “Erase Plugin Data” and Save
4. Go to Connection tab on ?”Marketing > Pinterest”
5. Disconnect your account by clicking on “Disconnect”?
6. Deactivate and uninstall “Pinterest for WooCommerce”
7. Install again “Pinterest for WooCommerce”
8. Restart the Pinterest onboarding
Hope this helps, please let us know the result.
Best
Diego
