## FAQs

<AccordionGroup>
  <Accordion title="Why can't I change my ringtone on web?">
    The web and desktop versions use a standard ringtone for consistency across browsers. For custom ringtones, use the mobile app where you have more flexibility with system integration.
  </Accordion>

  <Accordion title="Do my preferences sync across devices?">
    Theme preferences sync across all devices logged into your account. Audio settings are device-specific since they depend on the hardware connected to each device.
  </Accordion>

  <Accordion title="How do I fix audio echo during calls?">
    Audio echo usually occurs when your microphone picks up sound from your speakers. Try using headphones, reducing speaker volume, or moving your microphone farther from speakers. In audio settings, ensure you've selected the correct devices for input and output.
