You can use the Bulk Edit feature to make changes to multiple campaigns or ad groups simultaneously, including updating the status of your ads.
To make bulk edits to ad status:
Log in to your TikTok Ads Manager account.
Click the Campaigns tab at the top of TikTok Ads Manager.
Use the Campaign, Ad Group, or Ad list to select multiple campaigns, ad groups, or ads using the checkbox next to them.
Note: Deleted campaigns and ad groups still exist in your account but cannot be edited.
