Unable to apply Content Credentials

Content Credentials can only be applied to files that are in JPG or PNG format. They can be applied to up to 50 files at a time, and each file must be no larger than 20MB.  Content Credentials can’t be applied when there are connection issues with another service. To resolve this, try applying again once the connection is restored.

Content Credentials can’t be applied to the files which: 

• Are corrupted 
• Are less than 256x256px in dimension 
• Uses a color space other than RGB (CMYK) 
• Have other Content Credentials applied to them that are collectively too large to store in the cloud.
