Before you can use a document offline, ensure that you open it and the cloud icon is not displayed next to it. (Adobe XD does not display the cloud icon.)
In Adobe Fresco, you can make a document available offline without having to open it. Tap the More options icon on the cloud document thumbnail, and select Make available offline.
Before you go offline, always open the cloud document on the device and in the app in which you want to work offline.
