When starting a recipe from the app the circulator starts but after 2 secs says time is up and stops

Just bought the WiFi model and setup and connection worked fine. I did a test run on a poached egg started from the app, worked fine . However, after that when I try a new recipe the circulator starts and then stops immediately saying time is up. I have of course tried cancelling the current recipe (pushing the green “x”) and restartet the machine by unplugging. Is this a common problem? How can it be fixed?   

@Ole Henrik Rostad Hmm…haven’t heard this one before. Are you on Android or iOS? Also, have you tried deleting / re-installing app?
