Hi, Welcome to the Samsung Members Community Canada. Please perform clear cache on your phone. To clear cache, go to Settings, swipe to, and touch Apps. Swipe to and touch the app you want to clear. Touch Storage, and then touch Clear cache.

Also, check if there is any app or device update available.

If the issue still persists, try to reset the hub and try activating it again.
