How update data cache for Shiny server?

Does anyone know how to have "fresh" data for R Shiny app web sessions?

Thanks

Could you make a minimal REPRoducible EXample (reprex) about your issue?
Here is a very useful guide about how to make a reprex for a shiny app

Shiny debugging and reprex guide

Shiny issues can be challenging to resolve relative to other problems with your code or statistical methods. Shiny apps are often large, complex projects with interacting files. When seeking help from others it is considered polite to: First, do your best to work through RStudio's debugging tools to diagnose your issue on your own. Often those shiny logs and tracebacks are useful to others trying to help out. Second, strive to minimize the effort required to replicate your issue. You can do this with a reproducible example ("reprex"). Shiny Debugging Errors in Shiny code can be difficult to track down.

Here is a trick I found from comments on forums - keep date of "app.R" creation file fresh

    p <- paste0(getwd(), "/app.R")
    
    # 2. Update file 'date creation'
    Sys.setFileTime(p, now())
    
  }) # onStop
