There appears to be an issue with setting up scenes on additional devices/phones that a sonoff device has been shared to. Schedules show up fine on the shared devices menu and can control the unit but scenes on that shared device can't be set up. It just says " no devices available" in the scene menu. I understand that scenes themselves cannot be shared but I would have thought they could be set up from scratch on the shared device itself. Scenes work perfectly on the device the unit was initialised on /master user.
