Welcome to our Community and thank you so much for your first post. I am sorry that you're having some issues with the Connect App not recognising your equipment currently.
I have located the account from your Forum information and all is looking OK with the equipment here; your hub was recently rebooted.
If you could please uninstall the app on all devices and reinstall on just one device that would be great. Before reinstalling, please can you do a PIN hole reset of your Hub to restore to factory settings for us. Please hold it in for at least 60 seconds - wait for the Hub to fully reboot and sign in using the details on the base. You can reset the password when you wish.
Let us know how you get on and we'll go from there.
