Your account settings allow you to set a lot of preferences for your catalog and account. One of those preferences is to set a default setting on any new share and pitch links regarding allowing downloads.
Here's how to set the default download setting:
1. Click Account Settings from the user menu.
2. Scroll down to the Preferences section and click the toggle next to the Allow downloads on share links and new pitches by default option.
If the toggle is blue, downloads will be allowed by default on any new links you generate. If the toggle is grey, downloads will not be allowed by default on any new links you generate.
