Hello @Eternal_d ,
Please make sure all notifications are enabled to show on the watch.
1.Open the Galaxy Wearable app, tap Watch settings, and then tap Notifications.
2.Tap More under “Most recent on phone or watch.” Then, tap the drop-down arrow and select All to see all installed apps.
3.To turn notifications on or off for individual apps, tap the switch next to your desired app.
4.To turn notifications on or off for all apps, tap the switch at the top of the screen next to All apps.
Also check in Galaxy Wearable -> menu -> watch -> Notifications if "show while using the phone" is checked. If this setting is turned off, notifications wont be shown on watch when the device is in use.
