Linked Accounts has two separate controls, and mixing them up is the most common reason someone can see an ad account that a teammate can't.
Linked / Unlinked | Connected / Disconnected | |
What it controls | Whether Opteo works on the ad account | Whether the ad account shows on your Accounts page |
Who it affects | Your whole team | Only you (or the teammate you change) |
Counts towards your plan? | Yes, when linked | No |
Where to change it | Linked and Unlinked tabs | Connected column, or Assign Team Members |
Some examples
Your teammate can see an ad account and you can't. It's linked, but you're not connected to it. Connect to it.
Nobody can see an ad account. It's unlinked. Link it from the Unlinked tab.
You want a client gone from your Accounts page, but a colleague still manages it. Disconnect yourself. Don't unlink it.
You've stopped working with a client. Unlink it, so it stops counting towards your plan.
