Manual changes during the campaign might affect campaign performance in a negative way. If you would like to do manual changes in Meta always reach out to your Customer Success Manager to double check which impact this might have.
In order to merge campaign results (such as clicks, impressions, conversions), we use fixed naming conventions for campaigns, ad sets, and ads. Any manual changes to the names will likely break these conventions. As a result, our systems will not be able to identify a campaign and associate the associated data with your event.
This can disable campaign automation, which will most likely impact campaign performance. As a result, our marketing attribution models will not be able to properly evaluate campaign results and any editing functionality in our web application will result in errors.
We strongly recommend that you do not tamper with campaigns in any way, even after the campaign has ended, as this can result in data loss.
