Problems showing google sheet graphics using webviewer

I'm trying to show some energy consumption in my Android phone. The graphic is available in google sheet which was published and shows nicely when I load the URL using Webviewer. Nevertheless, when the data change and I reload the URL (after 1 minute for example), the webviewer sometimes show old graphics already shown. I don't know if this is a problem with this component or a problem with google sheet service. Does anyone know anything about or have notice this problem?

Probably google sheets. They it will refresh every 5 minutes or when republished but it rarely does.

Other ways (more complicated):

or use the native chart component in AI2
