@Adnan Shikh I'd start with Refreshing permissions as instructed on the message, see what happens then.
Although I'm pretty sure you won't be able to save it in a custom field, you may be able to visualize it in the Live Chat.
Hello Gustavo,
The first image is when I pressed on “Go to the catalog settings” and No refresh permission is showing.
You can refresh permissions by clicking on the 'Help' icon on the bottom left corner of Manychat.
Indeed, I refreshed permissions but still couldn’t see the details of the sent cart by a user
Adnan, how did you integrated a product catalogue to WhatsApp?
I’m not seing that option. I did everything from Meta Business Manager but it’s not showing for me :(
