/futures/data/takerlongshortRatio delay.

Why does this Restful Api delay so long?
For 1day interval, the delay even exceeds one day.

For example, AVAXUSDT_20240723_1d.csv I feteched:
local_time,time,run_interval,buy_sell_ratio,buy_vol,sell_vol
1721779454525,1721692800000,1440,0.9819,6006869,6117398

I keep fetch latest data in my program and the local_time is the actual time I got this piece of data.
