Don't worry! If you try and connect your Flow and you get a message saying that your Flow is already associated with another device, you can take a few easy steps to get reconnected.
Why does this happen?
Flow can only be connected to one account at a time. Once your Flow is associated with an account, it must be dissociated before it can be connected to another account. Here's how to dissociate your Flow from an account.
Step 1: Dissociate your Flow from the original account
A. Go to the settings section in your Flow app
B. Tap "My Flow"
C. Hit Dissociate
Step 2: Reset your Flow
To reset your Flow to the original factory settings, all you need is a paper clip (or something similar).
A. Hold down your Flow's main touch button
B. Find your Flow's factory reset button (see below).
C. While holding down the button, gently insert the bent paper clip into the factory reset hole on your Flow and push and release the reset button once.
D. Let go of your Flow's main touch button
Your bottom LED will turn blue for approx 15 seconds. Once it goes out, your Flow has been reset. When you push your Flow's main touch button, you will see scrolling blue LEDs, indicating that your Flow is ready to connect!
