Steps to reproduce

1.I followed the Visualize COVID-19 case data in a blink of an eye — using R, Shiny & Plotly tutorial
2. I created a new free account at shinyapps.io,
3. Initially, when I attempted to publish, I saw the following output: Error when trying to deploy to shinyapps.io: application depends on package "crosstalk" but it is not installed. Please resolve before continuing. This is repeated for a number of different packages.
4. Following the advice here, I ran the following in the console:

install.packages(c("crosstalk", "data.table", "fastmap", "hexbin", "htmlwidgets", "httpuv", "httr", "later", "lazyeval", "plotly", "rsconnect", "shiny", "sourcetools"))

5. I then added the following lines to the beginning of ui.R, just after the libraries shiny and plotly are loaded:

library(crosstalk)
library(data.table)
library(fastmap)
library(hexbin)
library(htmlwidgets)
library(httpuv)
library(httr)
library(later)
library(lazyeval)
library(rsconnect)
library(sourcetools)

6. During the publish process, I included all the files. (Simply including server.R and ui.R leads to a page with just a <pre> tag error, and no interactive content.)
