Hi Maxime,
Thank you for reaching out to us. I see that you have issues with hitting your manager account limits and was wondering if there are any best practices that we recommend. According to
this document, if you happen to hit your limit on the amount of accounts your MCC can manage, we recommend that you create a new parallel top-level manager account to handle new client accounts. Let me know if you have further questions.
Thank you,
Bryan, Google Ads API Team
