Required permissions are missing for the app

We have a problem with the FB lead form.
Leads are not arriving from one form!
All the other forms are working and sending leads.

This is the error we get:
"Required permissions are missing for the app."

Everything is connected correctly on Facebook—proof is that the other 10 forms work fine.

How can we fix this?

Hello @guyseo,

Could you please confirm a few details so we can better understand the issue and assist you more effectively?

1. Is the page you are trying to connect owned by you?
2. Was the page created before you first connected with Facebook, or was it created after establishing the connection?
3. Please share the workflow URL where you are facing this issue so we can investigate further.
4. Lastly, confirm the trigger event you are using.
