About two hours into an 18 hour cook Joule shut down. I checked the app and it said (in a snotty, bratty tone) "I need an update". Joule did not accept attempts to wait for the cook to be done so I had to pull out the PolyScience Sous Vide Professional to do the job. If I had not had a back-up, I would be way more than pissed. When I tried the update, it failed. only like five times.
Really guys, software needs to be friendly and if you are already cooking, it should calmly wait its turn.
