Did you get this fixed? I had this issue with one of my devices and so did someone else - we talked about this here - [OBSOLETE] HomeSeer Dimmer and Switch (HS-WD100+ / HS-WS100+) Device Handlers - #175 by nickha The devices were both using custom code.
Are your devices that failed to display using custom code? If so what handlers are they and do the names have any special characters? I’m on Android with this but I’m just wondering if this is a bigger issue affecting more people with the new app in general.
