I bought 3 smart plugs and set them up one after the other. When setting up, schedules 2 work perfectly. One plug however does not work properly. After the off time has passed the schedule does not show in the devices part ot the app. The on and off times are still within the setup part of the app. For example device set to switch off  0630. When the time goes to 0631, schedule disappears. Tried setting timezones uninstalling/reinstalling etc. Any ideas?
