How long does Ava bracelet take to work?

Excuse me, I'm curious about the Ava bracelet and its functionality. Could you please elaborate on how long it typically takes for the bracelet to start working after it's been activated or set up? Is there a specific process or waiting period that users should be aware of before expecting it to function properly? Additionally, are there any factors that could potentially affect the bracelet's activation time or its overall performance? Thank you for your time and assistance.
