Delay syncing chart on UX

I create a table and dynamic chart on google sheet(DATA Ref.) and express the chart it on AppSheet UX (Public the chart in pdf URL).
Every time I input the data(AppSheet UX) and sync, The DATA and CHART in google sheet changes but the express chart(UX) isn’t changed as the DATA change. (It takes approx 2-3 minutes to be synced)

Would anyone have any advice? Pleaseeeee…

It depends. What kinda chart? Are there sheet formulas? How much data are you plotting? You are viewing the chart as PDF - well that probably takes more time than if the chart was SVG or PNG.
