You have successfully connected your Qi Aerista Smart Tea Brewer. But some time later it always shows as offline and fails to respond to app commands. What to do next? You may need to delete the brewer and redo the connection process again. Here is what you should do:
1. On the Brewer screen, click on the Connection icon at the top left corner.
2. On the Device List, swipe to the left on your brewer. You should then see a garbage can or DELETE (see attached pic).
3. Delete your brewer and go through the connection process again to connect it to your app.
