Accounts/campaigns/adset/adv delete
At the moment, you can only delete accounts from Dolphin.
Correspondingly, what was tied on these accounts will also be deleted: advertising cab, campaigns, adsets and advertisements.
In order to delete an unnecessary account, select it on the Accounts tab in the Ads Manager 2.0 interface and click on the "Delete" icon.
There is no campaign/addet/announcement feature at the moment, but it is planned to be implemented.
