The easiest way to ensure specific content is set to post to specific accounts is to use categories and update the default accounts for your content in bulk.
This is also super handy if you change or add to your default accounts as our system does not retroactively change these settings for preexisting content in your library.
To begin any bulk operation, go to your Content Library, click the gear icon in the center of your screen, and select 'Bulk Operations'.
In 'Bulk Operations', Click Select Default Accounts.
Click 'Select Content', select your content items or categories, and click 'Add Items' at the bottom left of the screen.
You can remove all existing default accounts by checking the box. To add accounts, hit 'Select All' or click the corresponding circle of each account you want to set as default.
Click 'Add Default Account(s)' to save the new default accounts.
