Terrible Even now after upgrading my broadband to full fibre with 30Mps upload and 150Mps download the notification is so slow the visitor has left before the app opens. I've tried deleting and reinstalling the app as suggested by nest but no improvement. This only seems to have happened since Google took over the log in. I came to Nest because the Ring doorbell was terrible and the Nest one was great in the beginning not it's virtually useless
