Can you please tell me how to link an existing ad account with Facebook business Manager so he has not requested to start to make some initial payment? Since I want to run ads on the basis of numbers and without the connected business Manager it is simply impossible to do!
That's what displays when you try to add a new custom audience (to add a file with the number base)
Ie will have to spend some amount of money (also not clear how much) and then I can add a file with the audience?!
Or can this new ad account to link with my other Business Manager om, which already was the money spent?
