Do you have a Smart Aroma Diffuser Pro from a recent delivery, and did it spray non-stop after you set a schedule in the app? Or did you see the message Schedule on this Pro: update within a few days in the app? Then your Pro has new firmware from the factory. Older versions of the app set a schedule on it incorrectly. App version 2.0.7 fixes this and is available in the App Store and Google Play. There's nothing wrong with your diffuser, and you don't need to return it.
1. Update the app
Open the App Store or Google Play, search for Scentech and tap Update if that button is shown. Your version is shown in the app under Settings › About the app: 2.0.7 or later is fine. The message about the Pro is gone after that.
2. Still spraying non-stop? Reset it
Hold the on/off button for 5 seconds. The Pro then does a factory reset: it stops and the schedule on the diffuser is cleared. Then add it again in the app via Add diffuser. If the app asks There's already a schedule on it, choose Start over.
3. Set your schedule in the app
Choose a schedule as described in Setting up a schedule. Set the timer button on the Pro to Smart, and it follows the schedule from the app. On 1H, 2H, 4H or 8H it runs for that time via the button.
A Pro with this new firmware beeps briefly when a schedule is saved. With a schedule of several blocks you'll hear several beeps. That's normal.
