I have the issue with some area of my application gets "gray out".
My application gets refreshed every minute for the latest data, and I am not sure if that causes it.
I use "invalidateLater(60*1000)" for the refresh.
After looking into the below link:
https://shiny.rstudio.com/articles/reconnecting.html
I have added the additional line:
session$allowReconnect(TRUE)
But the "gray out" still persists. Any help would be appreciated.
