Hi Abo, 

Welcome to Box Community and glad to assist! 

Most of the time, aggregates will be updated within an hour or less. For larger changes or more complex folder structures, aggregates may take up to 24 hours to be correct.

Thanks for posting!

I am wondering what to do if the aggregate doesn't get corrected after waiting for a very long time, like for a week?

Should I post another request again? Thanks.
