I’m having a big issue with connectin devices to my Homey. When trying to add a device I get a error saying: n.rf.getState is not a function. Just wrote about it in this [post](https://community.homey.app/t/app-pro-device-capabilities-enhance-the-capabilities-of-devices/43287/2128) in device capabilities, but I now noticed that I get this error when trying to add devices from all of my apps. Some of the apps still lets me add a device, but quite few doesn’t work at all. Anyone know what this can be? Tried restarting the Homey without any luck. ---

Here’s another one: [Can't add any new devices without an error](https://community.homey.app/t/cant-add-any-new-devices-without-an-error/150153) Looks like a bug in the mobile app, you should contact Athom about it. ---

It’s already reported directly to Athom. Seems to be a WebApp issue. You can try to add devices in mobile app. It’s reported by users that it should work this way. So please do not spam Athom suport 😄 Edit: Response from Athom: it’s fixed now 🤞 ---

Hi, if I try to add a new Shelly Device or an new Dashboard Controller or any other device I get that error from my screenshot. It does not matter what app I try. The screenshot from the Shelly App is only an example ![grafik](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/f/7/f7211a69adcf7318c732a978e720518234ea3af6.png) “n.rf.getState” is not a function. I have already restarted my homey. Can you please tell me what I can do about this? Thank you ---
