My Shiny App runs perfectly well on my local server, but when I try to run it on shinyapps.io, it takes quite a while to load, and when it finally does, it immediately disconnects. I'm assuming this is happening because it has to load too much data (it loads two DFs, both of which contain several million observations), but I'm not sure. For context, I only have the free account on shinyapps.io, so that may be limiting performance. Should I find more efficient ways to load the data (e.g., with something like the arrow package? I don't have any experience with this.), or is there potentially something else going on? Thanks!
