I am a shinyapps.io Professional License user and since yesterday I have started getting the dreaded 503 error when trying to access multiple instances of my app. This feels like a new issue given I haven't had a problem for months and hadn't changed the configuration on the shinyapps.io config for the app. In fact, I believe this shouldn't be happening given how I have configured my app at all:
My app is chunky and we have always for roughtly one instance per user/connection/worker, but since yesterday this seems to have stopped working. Has anything changed in the back-end or is scaling suddenly behaving differently to how it had been?
