Dash dropdown not working after a while

Hi Dash,

I use a dropdown list option to update table using dash on dashboard, it works fine when I open the dashboard, while it does not work after a while. Let’s say, if you do not touch it for an hour, come back and select something from dropdown list, and no responding. So I have to refresh the page and get it work. What could be the reason and how to fix it? I am using Google chrome, Edge shows the same. thanks a lot.

Hey @abeljiang2, welcome to the community.

How is your app deployed? Do you get any error messages?
