Why can't I change the weather delay or any of the boxes on that row?
In order to change alert settings for weather delay notifications from Procore, you must be a user with 'Admin' level permissions on the Site Diary tool. Typically, this permission is granted to your Procore Administrator or to users who are in charge of administering specific Procore projects at your company.
To learn how to change the weather delay for a project. See Enable Weather Delay Alerts by Phone or Email.
