I was recently hired by a client to fix their Facebook Business Manager account, which was not working properly. After conducting a thorough analysis of the account, I found that the issue was caused by a mismatch between the Facebook Page and Ad Account linked to the Business Manager.

To resolve the issue, I first disconnected the incorrect Ad Account and then linked the correct one. I also checked and made sure that the Facebook Page had the proper permissions for the Ad Account to access it.

Additionally, I checked the settings for the Business Manager and ensured that all necessary permissions were granted for the Ad Account to run advertisements.

After these changes were made, I tested the account and confirmed that it was now functioning properly. The client was very satisfied with the resolution and was able to continue managing their Facebook advertising campaigns with ease.

In conclusion, fixing the client's Facebook Business Manager required a combination of technical expertise and attention to detail. By identifying and resolving the issue, I was able to help the client improve their advertising efforts and reach a wider audience.
