Apologies if I've missed documentation somewhere. When checking the network protos available WebSockets is always greyed out. The response to /info always has "WebSocket": false and we downgrade to xhr-streaming.
When running the shiny app locally in RStudio then WebSockets is fine.
There are a few bug reports regarding Connection headers and a few other ideas but are they relevant to the shinyapps.io saas?
Update: Using RStudio and rsconnect I see
rsconnect::showProperties(appPath = getwd(), appName = "xxxx", account = "xxxxxx")
However I haven't seen this in the dashboard, nor can I edit the property...
rsconnect::setProperty("application.shiny.websockets", TRUE, appPath = getwd(), appName = "xxxx", account = "xxxxx")
Error: HTTP 400
Unable to set read-only property.
Anyone know why this is disabled and seemingly uneditable?
