In Cometly, it's important to note that a single ad account cannot be linked to multiple spaces simultaneously. This restriction is due to the limitations set by the ad platforms on API calls.

To link an ad account already connected to one space with another space, you have two options:

A) First, disconnect the ad account from its current space and then connect it to the new space.

B) Alternatively, you can create a new ad account and link this new account to the desired space.
