My shiny app was running perfectly well for I'd say almost a year, at least 6 months.
Now when I try to access it (or other people from other computers) it says "please wait" for eternity.
I have not redeployed the app recently . I haven't changed anything from my side. As I understand all of the files are uploaded on some Shiny server. So I don't know what has happened.
Any advice ?
