ATLAS FormBuilder - Deleting Phase Permissions
It can be beneficial to delete a phase permission from your form in certain circumstances, whether you wish to remove an accidentally-added section from a specific phase, or to remove view/edit permissions for a specific user or users in one fell swoop.
To delete an existing phase permission...
Step 1 - Navigate to your form's dashboard and select View/Edit Phases in the Quick Links section OR select Phases in the Data Collection and Form Lifecycle section.

Step 2 - Locate the phase in which the phase permission(s) you wish to delete is housed. Click the gear icon next to that phase.
Select Edit Phase/Permissions from the dropdown menu that opens.
Step 3 - A new section will appear on the right side of the page, containing two tabs. Click the rightmost tab labeled Permissions.
Step 4 - You will be presented with a list of every current phase permission in the selected phase. Locate the phase permission you want to delete, and click the red trashcan button next to it.
All the phase permissions that you have set up for that phase of your form will be displayed. Find the phase permission you want to delete and select the red trash icon next to it.
Step 5 - A confirmation message will appear to verify that you wish to delete the selected phase permission. Select the OK button to confirm the deletion.
Step 6 - Once you're finished making changes, click the Save button at the bottom of the section. Your deletions should take effect immediately!
