You can use the Exception List to exclude certain websites from showing the watermark, even if the Apply List includes them. To add sites to the exception list, follow the steps given below:
- Sign in to your Ulaa Admin Console.
- Click Switch to the Organization on the top right corner (skip this step if you're already in the Organization's view).
- Go to Policies > Watermark > Exceptions.
- Click +Add.
- Enter the website URL where you do not want the watermark to appear.
- Select the groups you want to enforce this policy to.
- Select the watermark configuration.
- Click Save.
