> Common questions about using NexRex.

<AccordionGroup>
  <Accordion title="My activities aren't showing up">
    Check **Settings → Connections** to confirm your device is still linked. If it
    disconnected, reconnect to resume sync. For Strava specifically, the row may
    show **Reconnect required** when the stored authorization was rejected —
    tap it to start a fresh OAuth grant. Opening the screen refreshes status,
    so the label updates as soon as Strava responds.
  </Accordion>

  <Accordion title="My weekly summary shows the wrong week">
    Recent activities may still be syncing. Wait a few minutes after your last run
    and refresh.
  </Accordion>

  <Accordion title="Can I switch between metric and imperial units?">
    Yes — change it under **Settings → Profile**. It applies across your plan and
    activity views.
  </Accordion>

  <Accordion title="What languages does NexRex support?">
    English, Traditional Chinese (`zh-TW`), and Japanese (`ja`). See
    [Account settings](/account/settings#language).

  <Accordion title="How do I join my coach's roster?">

    them once you accept.
