Unable to save responses even after enabling the save response option

The response of my http requests is not being saved and instead I see the below message upon every request.

1 changes could not be saved

You don’t seem to have the required permissions to perform these actions

This was working fine without any problems until I logged into the app with my email id and setup the account to be able to sync my data.

Can anyone please let me know the permissions I need to resolve this. thanks !

Thank you very much.
