I'm currently facing an issue on Facebook insights. Whenever I pull data, for example for the "Total Reach" metric, and split it by date, the sum of the aggregate values for all the days for a particular month will be different than if I split the data by month instead.
Is this a known issue or am I missing something here?
I can provide you further details upon request.
Thanks for your assistance.
Just to verify it's not the known issue we already are aware of for post-level discrepancies, can you check this article and execute the workaround to use the new endpoint that grabs all post data?:
