I recently noticed my device list was not updating. Devices would just stay on the online list even though they were clearly offline (and vice versa). I also plugged in a new device (hue bridge) via utp cable but it wasn't showing in the app. It did pop up a 'new device' message in message centre in the app, but just did not show up in the device list. So, I restarted the router, no change. Then deleted the app and reinstalled but now the whole device list is missing. 

I've got the feeling this all started since the last app update, but I'm not a 100% sure. Anyone having the same issues recently? And any suggestion on how to fix this?

FYI: App is v2.4.15 on iPhone 8 iOS 14.4, router is a Deco M9 Plus
