Does your user has write permissions?
Have you double checked the listviews if they’re set to editable too?
I believe they come as non-editable by default.
Hope this helps
Just an idea
Make sure that not just the Entity Access is set to Read, Write for the user role you are using, but also that the editability of your view was not set to Editable No
Find out where the blocking of editing starts. What if you add an attribute of ScrappingAuthorizationForm to the form? Is it editable? What if you add a Dataview of Supplier with Datasource via microflow DS_Supplier_GetOne. Is it editable?
