So I have a couple of Ads accounts – for each one under Access and Security, I see:

• Users – myself and colleagues
• Managers – my marketing agency A who run the account (owner: no) and me (I somehow set up a manager account, owner: yes)

I am thinking of switching agencies and talking to others, they want to see the Ads account to get an idea of what’s involved. I don’t mind this, but in my experiments, I see no way to prevent:

• Existing agency A being able to see me granting access to potential agency B
• Potential agency B being able to see that existing agency A is currently running it

Am I missing something? Or is this whole access model as much of a sh*tshow as it seems?
