Thank you for your response. Are you able to let us know what device you are accessing the on?
For your Apple device, if you're on iOS 15 then you can try this: Open Settings > Tap your name > Tap iCloud > Tap Manage Settings > Tap the Connect App > Tap Delete Data.
If you're on iOS 16 then just delete the app from your device, restart the handset, and then re-download the Connect App.
For your Android device, you can try this: Open settings > Apps > Connect App > Storage > Clear data / Clear cache.
If this also fails then we currently have a known error with some of the data in our systems that's causing the app to not recognise the Hub in a minority of instances. We're already investigating this as a high priority.
Pop back and keep us posted.
