A downloadable tool for offline campaign management and bulk editing
If the option to bulk upload companies isn’t showing in Microsoft Advertising Editor, a few things could be causing it:
Editor Version: Make sure you’ve updated to the latest version — some features may not be available in older builds.
Campaign Type Support: Bulk uploading for companies (like for LinkedIn profile targeting) only works in supported campaign types.
Permissions: Check your account access level; some roles may not have full editing capabilities.
Template Format: If you’re uploading via file, be sure you're using the correct Microsoft bulk upload template.
I ran into a similar issue a while back while switching between accounts during unrelated testing for a content platform (https://myfarzana.com) — it turned out to be an account-level setting. So it might be worth reviewing your account structure or trying the same action in a different account as a test.
Also, the web version sometimes reflects features better than the desktop editor. You could try that to confirm whether it's a tool issue or account-specific.
