Can I connect more than one ad account?
Yes. If your connected Meta profile has access to several ad accounts, you can choose which one to work in.
Switching accounts
Set the ad account for a chat from the account selector, and switch it whenever you need to. Everything you build in that chat applies to the account you selected.
Keeping accounts separate
To keep different accounts cleanly separated, start a new chat for each one. Each chat remembers its own account, platform, and pinned resources, so there is no risk of building in the wrong account. You can also change the selected ad account in Integrations.
A note on single-user accounts
A Mark account is for a single user today. Shared workspaces and teammates are coming later, so for now, one person manages the connected accounts. If several people need to work on the underlying ads, they can be given roles on the Meta ad account itself.
