I really liked the Smart Delta and this app until it stopped working. I have a Samsung S9+ and it has stopped working within the last 1.5 months. It will sync to the device, but as it is setting up the device, I get a notification that a problem occured and to try again. Uninstalling and reinstalling the app hasn't worked either. I would love for this to work, but am very disappointed right now. Edit: my friends iphone has no issue with connecting and setting up, so it's a non-apple issue.
