could it be because the button is at startup hidden(...) by, in the UI

 hidden(downloadButton("download_single_results", "Download results"))

later undone in the server side by

show("download_single_results")

which works on the good instance and fails to show on the bad one?

Yes, it was a function prevalence issue, corrected by replacing show() bu shinyjs::show()
